On one hand he's right: arab countries that used to be christian and jews didnt get replaced, they got converted, ethnically they are still the same (arabs) not some other race, tho a lot of mongol DNA from all the rape they got
On the other hand the muhazn part is bullshit, asians in general behave and are a tiny minority of which only a part are chinese and the rest are other ethnicity. The replacement is happening by amerindians (mostly mexicans) and also black people who are increasingly violent as if they want white people to become aggressive against them. Overall I say the asians actually got more to win from this since they could actually get rid of the competition from other minorities, and they are getting fucked by the "privilege" bullshit in work and college admissions just like the whites
TLDR: yang is a retard trying to play both sides
