If the US President incites hate and violence via Twitter we would be having the same discussion no?

No. We might be having a conversation about the inappropriateness of such comments, but we have no laws against hate speech. In fact, a sitting president can call for imminent violence against a person or group (which is illegal) and the only recourse would be impeachment or waiting until the next election (he can be prosecuted after his removal though). So there wouldn't be much we could do if the US President did call for violence.
