For instance -- I have the right to say 'Nazis should be punched in the face' in most circumstances. It would violate Twitter TOS to tweet that however and they'd be well within their right to take that message down or ban the account.
The 'spirit' of the TOS is civility in most part, not legality. Donald Trumps twitter account isn't civil.
And if you disagree about that, or about the spirit of the TOS so be it -- that is why things like terms of service are held to the more objective letter, and not the highly subjective spirit.
