I just hope your conscience won't torture you too much a few decades in the future when you'll see the Stalinist nightmare you contributed to.
For someone who claims to be an "anarchist" and arbiter of what leftism is, you sure do swallow a lot of right-wing talking points and conspiracy theories, like this one, where somehow telling people not to use hateful or hurtful language will somehow lead to totalitarianism; as if totalitarian censorship has anything to do whatsoever with telling people not to use hateful or hurtful language.
Unless you're lying of course, and you just want to chant slurs without any social repercussions. The fact that you said in the GitLab issue you linked to that playing a voice clip with the "R" slur in it is the only reason you play Xonotic, and that if it was removed you would stop playing, suggests as much. Perhaps it's you, the one trying to silence and demean criticism of bigotry, who is attempting to impose censorship; and not someone like me who just runs a website and is choosing what games to recommend.
