You are being disingenuous, because you only see the possibility on one side. I see it on both. So, I see how Trump is not different as you say he is. The threat is normal, as it always has been, and will be.
I prefer having a system which limits the president, regardless of party. You prefer having a system which empowers Dem presidents to act in any way, and limits GOP presidents, and that type of system necessarily leads to dictatorship eventually.
