There are many different ways to look at this issue and you manage to be an idiot in all of them.

Amazing.
One way to look it at is as a philosophical issue. Should entities have a right to associate or not associate with who they want? I think they should but you might have a different opinion, fair enough.
Another is from a legal standpoint. Did Facebook violate their terms of service when they banned you. My guess is no because they have enough money to hire fancy lawyers who'll word their TOS in a manner that will leave them free to ban almost anybody they want, but you can always try your luck.
The most recent standpoint, which you bring up here, the political strategy standpoint, well even in that you are a cuck. Nothing pathetic in disabling or disrupting your enemies communication or running more effective propaganda. That's how you win wars you dipshit.
