Discord has expanded its Hateful Conduct Policy to explicitly include prohibitions against misgendering and deadnaming in a policy update. Accompanying this policy update, Discord has also implemented a comprehensive warning system to enforce these guidelines effectively.
There it is.
1A is irrelevant, it only protects against censorship by the government. Discord is a private entity, they can do whatever the hell they want on the platform they own. They aren’t obligated to host your opinions, and neither are conservative outlets obligated to host liberal opinions. Get it right next time.
