I think leftists are pretty much the same everywhere. They oppose the concept of a Jewish ethnic state and they oppose the concept of any white (goyish) ethnic states. On the one hand they encourage the more intelligent peoples to cease having children (due to "overpopulation") but, on the other hand, they bow to the power of demography and accept the fact that less intelligent peoples (mainly "people of color" and Arabs) have more children and will, eventually, crowd out the former.
Yes, they are "intelligent" and (mostly) non-violent but they fail to grasp the reality that the peoples they promote are less intelligent (overall) than they and are more violent (overall) than they. This is also the reason they advocate such insane ideas as gun control.
