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.
Just like you’re free to say it, others are free to not listen. If an user blocks you then so be it - I’m sure you’ve blocked people as well. Downvotes on the other hand are equivalent to mean comments; it can just be ignored. Getting banned is a real risk though, I’ll give you that, but then again, you can just make a new account.
