Nexus consistently refuses to be a platform for bigotry.
That should not be controversial, at all, in any context.
If this asshat wants to publish it elsewhere - he’s free to. Nobody’s stopping him. It’s just a file. He has every moral right to modify software however he sees fit, and he has every practical right to be a homophobe online with fellow homophobes.
But I don’t want anything to do with him. I don’t want to use any website that’s cool with bigots spreading bigotry. If the people who run the website don’t want to deal with that shit either… tough shit, guy. Find another bar. This one’s not for Nazis. Warn all your Nazi friends.
