You can clearly tell you're a Marxist when you use words such as xenophobia.  It's almost impossible to use that term without being one.  Typically any non-homogenous civilization collapses magnitudes faster than homogenous ones (Japan, China, etc, that just keep trucking for thousands of years).  America is only an experiment in this regard of "diversity", and most unbiased observers would consider that part of the experiment failed or failing.

Conversely, when Asian civilizations openly act "racist" and hostile towards foreigners, while also enacting laws to prevent their civilization to diverge from being homogenous, liberals high five them like, "oh hey, Asian culture, so cool!".  Then if a white civilization anywhere does it on a macro or even micro level, here comes the liberals throwing a tantrum saying, "oh, homogenous is bad, white people are bad, diversity is good!  whites can't be allowed to organize for common self interests!".

This is why liberalism collapsed and is only made up of white male hating lesbians, central planning communists, and other lunatics now.  There isn't a group of more hypocritical, double standard scumbags walking the planet than leftist liberals.
