My brother in Christ, you are conflating free speech with the freedom from consequences. You are free to express your opinions. You will not be arrested for that. You can use the internet however you wish to express whatever opinions you have, no matter how stupid or hateful they are.

However, if your opinion sucks, the community will "deal with it" by down voting your dumb ass, and if you piss enough people off, you'll get banned. Your rights have not been infringed. You're just an asshole and people don't want to listen to you anymore. You can freely go complain about it somewhere else.

I'm sure there is a community on the Internet that would welcome your shitty opinions into their little echo chamber. Go there if you don't like it here. Or, as you say: "deal with it".
