That's something that people of SRC refuse to understand. And I think deliberately.
The way that extreme-right shithole keeps justifying its toxicity to itself is by convincing themselves they're just standing up to "bad moderators" (That they are banned for being racist, homophobic, sexually agressive wastes of human skin is tangential to people like you.)
What you deliberately refuse to acknowledge is that subreddit creators and moderators are free to, within a set of very broad guidelines having mainly to do with federal law and the continued running of the website, moderate as they see fit.
You as user have to follow the rules of the subreddit and that is just that. You do not get to claim any kind of special rights, you do not get to make any demands of a moderating team. Especially not when these demands, as they always do with people like you, boil down to refusing to accept we do not tolerate hatespeech.
Admins stand on record as saying that a subreddit moderator may ban you for any kind of reason at all, including no reason.
So please. Keep whining about your "free speech" (And keep disregarding the fact that the weakest argument possible to make in favour of a statement is that it is not literally illegal to make it.)
Keep pretending that you're not some kind of white supremacist, bigoted asshole who takes positive glee in dehumanising others for that very terrible crime of how they were born, who take great exception to someone else standing up for basic human decency, compassion and empathy.
Keep doing that. Let us see how far you will get with that, in a society that will forever move towards greater acceptance, understanding and humanity.
That was my rant. Stick it up your jumper.
Now go away, would you.
