That's a really weak argument.

1) It has nothing to do with racism but uses the accusation of someone being racist as a tool to push an agenda.

2) Japan still makes good sushi. Supermarket sushi has not destroyed japanese sushi culture

3) I'd argue that capitalism has made the world better in pretty much every aspect. You could argue that capitalism has destroyed the environment, but the fact is that leftist countries have a history of being even more destructive.

4) "white people have no culture" But people all over the world drink coke, watch american movies, drink french wine, eat italian food, drive german cars and they seem to like their smartphones.
