I disagree. It's important because admins have not been enforcing bigotry. George Washington was not banned for racism, he was banned for bigotry(*).
So.... we're enforcing a no-bigotry rule now?
I'm not saying they SHOULDN'T smack down all forms of bigotry, but that means laying the 500-word essay ban on everyone who uses words like "retard", "my old friend" or talks about the people of any nation in a negative way. (I doubt I would have to search hard to find plenty of examples of anti-American bigotry that have gone unpunished, so why the sudden crackdown on someone who said something about Mexico?)
(* - actually, saying that all Mexicans should be killed to stop the drug trade isn't even bigotry, really. It's more like, I dunno, either a hyperbole or just a really extreme, bad idea. Maybe we're banning hyperboles and bad ideas now. I don't know. I mean I am certainly a cheerful spokesman when it comes to banning people and I'm not real sure I'd miss George Washington, who I mainly think of in terms of him trolling the game at various times in the past, but I'm not on board with this particular ban.)
Racism is a type of bigotry, and afaik it's mostly left up to admin discretion what types of bigotry "count." I've seen mutes over homophobia and sexism before, and I'm sure there've been bans over the same and other types of bigotry. imo though, arguing this amounts to rules lawyering, which doesn't really get us anywhere. The real issue should be over whether admins judge potentially bigoted things in-context or in a vacuum. Obviously, if you were to just take what he said with no context at all, it would be extreme and bigoted to say the least, but in context it's pretty clearly not intended to be mean at all, just a (bad) joke.
