giving the administration the power to illegalize speech
Why would we give trump that power?
I mean, we could give him the power to illegalize nazi speech specifically. That would be fine. I bet he wouldn't use it.
I don't think you're thinking about this strategically. If you were playing magic the gathering, does hurting your opponent's life points mean they get to hurt yours now? Do you have to lower all your defenses so they can get a turn? No. We don't have to illegalize leftist speech either.
If they ever try to, be very angry.
