Okay, let's make this very clear: Freedom of speech most definitely applies to businesses.

just writing "let's make this very clear" doesn't mean you're correct. You may not impose your interpretation of "free speech" on any private business. I understand that you'd prefer it if you could, but those are not the facts on the ground.

freedom of speech is extra-legal, and if your kind succeeds in spreading this disinformation, we will amend the constitution.

...what? Like, the US constitution? Private businesses who provide regulations for the manner in which you may express yourself within them are themselves engaging in free speech. They are allowing you into their private space, contingent on you following their rules.

To amend the constitution to infringe on their private spaces would be a horrific overstep of federal power, and I'm frankly surprised you're advocating that.

Reddit is not a public park. Controlling discourse here is immoral and not acceptable by the populace. It is also codified that you may resist unlawful arrest, but people are executed for that every day. The law is not supreme to morality.

Correct, reddit is private. Just like a Meijer, or an office building, or a person's home. If you enter their space and violate the rules they've set out, then refuse to leave, no one is going to cry for you when you're arrested.
