Let's not keep making the mistake of assuming the rule of law matters at this point. If he does something and nobody stops it, its legality or lack there of is moot. If he says to do something and people do it and nobody stops him (or judge's rulings about it are ignored), then it doesn't matter that it was illegal.

I know you're just trying to get people to calm down, but at this point, people are right to be scared and right to think these things could actually come to pass considering it has happened before. Maybe it won't get that far... But plenty has already happened that should never have happened, and the US currently has a president who is illegally, specifically unconstitutionally, holding office and was allowed to be sworn in anyway, so it's probably not a good idea to assume this won't happen just because it's also unconstitutional.
