I mean... It was. SARS and other shit came out of China too. There's some nasty gnarly viruses coming out of China. I guess personally I don't think it's racist to be satirical about it. It combined the concept of Corona beer with a meme from the president. I don't think a shirt like that excuses any amount of violence I don't think that's anybody's intent.
When you say anybody that would want something like that is some bigoted piece of shit you draw a line in the sand and you put everybody on the other side.
Is it tacky and insensitive? Yeah. But people are extrapolating a whole lot of things here that aren't said or weren't put forth.
If the right can just be slightly less douchey the left will get slaughtered in this next election.
