So what you believe is Debate Politics really ought to have to carry e.g. racist vermin, but you might let them censor those people, and many others, because they're small?
Why? I think most of us like that the moderators on here do a good job keeping us in line, ban the vermin, and for those of us who remain enforce a set of rules that keep this place civil. I was infracted a couple of days ago for getting a little out of hand. I did then what I always do and thanked them for keeping the place civil, and I meant it. The system you favor would prohibit DP (if they were big enough) from all those efforts.
There is nothing illegal about calling another poster a f'in worthless POS idiot. There's nothing illegal about attacking someone because they are a woman, or gay, or black, or brown. It poisons the discourse, but you'd require Twitter to permit that on their site or else. I don't get it.
Just for example, if a black woman is on Twitter, there's nothing illegal to post below every one of her tweets some version of, "you're just a worthless n-word, c-word - go back to Africa!!" That happens all the time. There is no threat of violence, just someone expressing their "viewpoint" of black women. I've seen the screenshots from black women, women of all races, Jews and others, of the kind of abuse that's pretty common online, and it's obviously not limited to them. You'd require Twitter to put up with that kind of abuse, and won't admit that's what you WANT to happen. It will happen, and you'd force Twitter to allow all of it, so you favor that outcome.
I think what it comes down to is you like DP because they don't censor the MAGAs or right wingers, conservatives, libertarians, etc. That's fine - I appreciate that as well. Makes the place interesting to have different "viewpoints." But they DO censor the vermin, and we all like that they do. The problem is when government demands that a place not censor "viewpoint", are compelled by government to provide a platform to every "viewpoint" (so long as it's not illegal or threatening violence) you can't just demand that they carry the MAGAs, but virtually EVERY viewpoint, not matter how deplorable and divisive and poisonous to the discourse, and that means the racist trolls etc.
There's a reason in a free society those decisions are left to the owner of the platform, and not compelled by government. If you want to host a website that allows the vermin free run, YOU CAN DO THAT!!! No one you want to visit will visit, unless you like the vermin, but it's your choice! Government cannot prohibit you from hosting the neo-Nazis - their speech is in fact protected. But neither should government force you to, or else.
