First and foremost, I’ll say right off the bat that I do not condone targeted mass hate campaigns against individuals or groups. I personally condemn that activity across the board no matter the victim or antagonist in any conflict, for any reason. That said, there’s a terrifying precedent being set currently that’s going to enable certain groups to change the world in ways previously not possible.
First, we need to identify how speech is protected on the internet. Currently there are no laws on any books anywhere that guarantee a person has access to the internet. There are also no laws explicitly stating that a company has to, in good faith, do business with everyone who approaches them for service regardless of who they are or what they believe. There are no laws regulating platforms on the internet that ensure every individual has equal access or ability to use them. There are no laws protecting forms of speech on the internet uniformly. There aren’t any real protections in place anywhere in federal regulatory bodies or federal or state governments on the whole. You can fall back to the first amendment, but the first amendment says fuck all about corporations being required to propagate your ideas. There are no such protections in place.
