"ALL lefties have always been for closed borders."

Bojidar Marinov has asserted on Facebook that "ALL lefties have always been for closed borders. Even today. Closed borders have always been the Left's policy, from Karl Marx until our day."

Even a cursory examination of the available evidence, however, shows that is nonsense. Laughable, really. Let's check reality:

"The Socialist Party works to build a world in which everyone will be able to freely move across borders, to visit and to live wherever they choose. We recognize the central role global capitalism plays in forcing the immigration of people from the less developed to the more industrialized countries, often leading to further economic and social injustice.
• We support secular democratic states, assuring equal rights to every citizen and resident in accordance with the Universal Declaration of Human Rights.
• We oppose the militarization of the United States/Mexican border, and an increase in the service budget instead of the "military" budget of the INS.
• We defend the rights of all immigrants to education, health care, and full civil and legal rights and call for an unconditional amnesty program for all undocumented people. We oppose the imposition of any fees on those receiving amnesty."

“– 22 – What will be the attitude of communism to existing nationalities?
The nationalities of the peoples associating themselves in accordance with the principle of community will be compelled to mingle with each other as a result of this association and thereby to dissolve themselves, just as the various estate and class distinctions must disappear through the abolition of their basis, private property.”
--https://www.marxists.org/archive/marx/works/download/pdf/Manifesto.pdf

“The Communists are further reproached with desiring to abolish countries and nationality.
The working men have no country. We cannot take from them what they have not got. Since the proletariat must first of all acquire political supremacy, must rise to be the leading class of the nation, must constitute itself the nation, it is so far, itself national, though not in the bourgeois sense of the word. National differences and antagonism between peoples are daily more and more vanishing, owing to the development of the bourgeoisie, to freedom of commerce, to the world market, to uniformity in the mode of production and in the conditions of life corresponding thereto. The supremacy of the proletariat will cause them to vanish still faster. United action, of the leading civilised countries at least, is one of the first conditions for the emancipation of the proletariat.”
--Ibid.

"Whereas, the working-class, democratic answer to these methods of divide and conquer and super-exploitation is working-class democratic internationalism. We see all workers everywhere, with or without papers as brothers and sisters. We give solidarity to democratic peoples struggles against imperialism and corporate global power. We fight against all forms of exploitation, and against discrimination on the basis of race, nationality, gender, sexual preference, or immigration status. Workers are workers, with or without papers. No human being is illegal. We fight for full legal rights for immigrant workers here today and those who come in the future. To build multiracial unity of workers and people, citizen, documented or undocumented, is the only way to move forward for democracy, economic and social justice, and socialism. Increasingly this involves opposition to the fascist-tinged anti-immigrant movement that is being fostered by the ultra-right in the form of hate speech and vigilantism directed against immigrants, especially those of color... The rapid legalization, without discrimination or onerous conditions, of all undocumented workers and their relatives living in the United States. The creation of mechanisms whereby immigrant workers in the future can come to the United States legally and safely with full rights."

"The undocumented immigrants who are already residing and working in the United States, and their families, should be granted a legal status which includes the chance to become U.S. citizens. Persons should be excluded from this process only if they present a clear and present danger to other members of our society. The level of fees required for this process should not be a burden on low-income workers. In any path to citizenship created to provide an orderly and appropriate resolution of the status of persons currently in the United States without proper documentation, we demand a recognition of past, uncredited payments into the Social Security System as part of any fees assessed for regularization of status. In regard to who should have a right to come and live and work in the U.S. we believe the following policies are fair:
The Green Party calls for permanent border passes to all citizens of Mexico and Canada whose identity can be traced and verified...
All persons fleeing political, racial, religious, or other types of persecution must be welcomed and given permanent resident status...
We oppose the militarization of our borders, (mis)using the National Guard as border police, and building a wall between the U.S. and Mexico...We must resist proposals that use illegal immigration as an excuse to put us all under further government monitoring and control by means of a national ID card or other identification or tracking systems..."

"Face notamment aux drames qui se jouent aux portes de l’Union européenne, le Parti socialiste souligne l’importance de bâtir une politique de migration globale, durable, responsable et coordonnée mais également de poursuivre sa politique d’aide au développement et de soutien aux réfugiés. En parallèle, les progressistes doivent défendre une vision positive de l’immigration, qui, à contre pied des contrevérités et amalgames multiples, sache mettre en valeur ses caractères positifs tant pour les migrants que pour les pays d’origine et d’accueil."

"Restablecimiento de la legalidad de los pasos fronterizos: respeto a los derechos humanos en la frontera sur

Pondremos fin de forma inmediata a las devoluciones ilegales de personas en las zonas fronterizas, que contravienen la legalidad internacional. Para ello, derogaremos los artículos correspondientes de la Ley Orgánica 4 / 2015, de 30 de marzo, de protección de la seguridad ciudadana.

Igualmente, pondremos fin a las vulneraciones de derechos humanos que se producen en la frontera sur. Para ello, eliminaremos los elementos lesivos colocados en los perímetros fronterizos de Ceuta y Melilla y promoveremos la adopción de un protocolo de actuación de los Cuerpos y Fuerzas de Seguridad del Estado en esta frontera sur. Además, revisaremos el tratado bilateral con Marruecos, a fin de garantizar el cumplimiento estricto del principio de no devolución."
