Someone mentions something about chess. Someone comments. Somehow, things get off-topic, maybe a casual comment that wasn't meant to be so casual, something like, "Oh, you're being such a (Insert political party here.) In other words, you're being dumb." Something like that could, and does easily happen, but the mods stop it.
But in your version, a fully-blown debate would happen. And instead of adults being discouraged or bored by the lack of politics, (I assume that happens with people,) they'd be excited to share their ideas with all the little kids coming on. Or, at least they'd be excited to put their opinion out there for other adults or older kids to see.
Then politics would be a bigger part of chess.com, and expand over time. People will eventually be known for their political opinions, and, over time, the "major forumers," most of whom are kids with lots of time on their hands and were in need of a hobby like chess, would turn into adults.
I'm not saying that the whole chess website would turn into a political brawl, I'm just saying that it would become a bigger part of chess.com, which is exactly what chess.com does not want. Which is why there are many other websites which have free speech. (Mostly websites that aren't that big I mean.)
(Note: When I was typing, "political," and "politics," other controversies could be used like religion and other stuff.)
If we were allowed to voice our opinions in public forums...
Well let's just say that would be a disaster, at least I feel it would be that way.
It's called "free speech". What would you prefer?
Ok.
First: Chess.com has the right to censor anything, it's their company and all that. Just want to get that out of the way.
Second: If there was free speech on a chess website, (It's a great idea elsewhere... too bad everything's being unfairly censored,) Then the chess website would turn into politics and controversy. Let me write out how I think it would happen.
