Good Post...The reason they keep changing the name is because it doesn't work! It's a favorite tactic of the socialists...if you give something a benign sounding name it will work better because it sounds good. A broken leg is a broken leg, calling it well doesn't make it work any better!
Yes it is: populists, egalitarians, jacobins, socialists, anarchists (in the leftists sense), communists, democrats, liberals, reds, bolsheviks, enviromentalists, and so on.
These are all synonyms, and I dont have anything against enviromentalists, however it is obvious that all these movements have been infested by the same leftists that have caused all the troubles in history.
