When someone is high profile they will be treated differently. That's just the nature of being high profile. Trump has said a lot of things that would have gotten you or I banned if Twitter noticed. Twitter let Trump slide for a long time, and is finally moderating some of the most egregious examples.

And to be clear, anyone calling for violence should also have similar actions taken against them. But, me shouting get out the guillotine to my 10 followers is different than POTUS saying the same thing.
