Is it wrong to eat Chinese food from a buffet?

I am seeing more and more insanity online as of late.

This guy is clearly trolling the other person. He claims he led a campaign to shut down a local Chinese buffet because white people were eating there, which ultimately forced the Chinese owners onto the street.

Now this may be a good troll, but it is the logical conclusion. If nobody is able to eat food or wear clothing or use tech that another "culture" invented or created then a lot of people aren't going to be able to use electricity or cars or roads or whatever.

Is is extremely arbitrary and pretty pointless to enforce such stupid things, while at the same time if someone makes a fool of themselves you can still laugh and point at them. But if we want to progress as a society we need to learn that all this fucking divisiveness is getting in the way. For all of you out there who say that we are "all united together" you realize how it is an oxymoron to also say someone is appropriating the culture, because "being united together" takes away our differences(hey look at that, communism!).

Be nice to people, educate, and grow. We are all humans and this insane divisiseness isn't healthy.
