Indeed, while I did not discuss it in the OP, governments of the West are importing millions of immigrants from countries least developed and infused with testosterone suppressing chemicals. An incessant and strident complaint of many laments the increasing result you predict exactly, which is derogated by official government and enemedia propaganda as nothing but virulent racism.

This importation has the result of afflicting those immigrants and their issue with the chemical castratants, amongst various benefits to the ruling class, including fostering ever widening division of society that increases it's susceptibility to despotic tyrants.

While Trump was primarily elected by concerns about illegal immigration (at least in the minds of many rust belt voters), today that importation of immigrants is higher than ever in the history of the US. The proposed wall is as unnecessary to exclude immigrants as it is necessary to tyranny. Military incursions might be prevented by a wall, but as we see from history, walls do prevent escaping despotic totalitarian oppression.

Immigrants are easily discouraged with enforcement of laws against availing them the blessings they seek, of employment, licenses, and so forth, yet we see those blessings being increasingly provided to them today in the US, which no wall will affect.

Thanks!
