Damn.

I don't think how you reacted is exactly okay (because you escalated the situation to violence, essentially), but I can't even go with E-S-H because what he said is really fucked.

It's not about politics anyway; it's about the fact that he literally told you your existence is racist, which is comical (seeing as how him saying that is itself ridiculously racist), but it's mostly just disgusting.

Sorry that happened to you. Don't pay for his dry-cleaning. He's a crusty dildo.

Please do your best to stay safe as well. He sounds like he has a potentially dangerous sense of entitlement and may come after you in some way.

Maybe don't directly admit in writing what you did, either, just in case he tries to sue or something and uses that as evidence.
