YSK: On the internet you can just freely say what you really think even if you know it's unpopular.
This isn't your college or work place break room. If people are saying something you disagree with you can just say it and you won't be fired or ostracized for it. Yeah, people will probably get angry and say mean things to you but those are just words which can be ignored. Offence is taken, not given.
This is mostly for the lurkers who upvote unpopular opinions but don't comment. You can speak up - you're not alone.
I literally just blocked another troll before seeing this post, that's literally ostracizing.
It was a 4 day old account too, so in all likelihood they were ostracized before, it was a negative consequence, and if it continues to happen. Maybe someday they won't immediately be a troll on a new account.
But if normal people do that, the trolls only get replies from each other and that's not fun for them.
Individual users blocking other users isn't what I mean by being ostracized. If the majority of users did then maybe so but that basically never happens no matter what you say. Being blocked by someone comes at no cost to the person getting blocked. They won't even know.
