@Ste1lar Additionally, if you are a "free speech" crusader who thinks people should be able to say whatever they want, damn be the consequences, then it's ridiculous to complain when people block you or your instance.
I do not know if that is how you personally feel or not.
Other instances are obviously not obligated to federate with your instance -- regardless of their reasons -- or allow nastiness on your instance to further propagate.
