Well thanks for phrasing that so nicely. I know it's offensive to some people but it's also exactly my kind of stupid humor. It's been a bit of a moral conundrum for me, I don't want to be an asshole to people who haven't done anything, but I also don't want to self censor. Currently though, for any new accounts that I create, I prefer another username anyway, but for this one, inertia is winning.
If so, I kindly encourage you to consider a new username. It is sad to see people slurred just based on who they are.
