Is he?
Now I don't really think he's going to do as much damage as many people fear. But that doesn't mean this isn't a massive defeat for civilisation.
It's not that he's literally going to make people's lives worse so much that he sets a really ****ty example in terms of moral attitude. The fact that his racist, sexist, ignorant ass made it into the white house is sending the message that it's possible to get away with the kind of uncivilised crap he pulled, and to even be rewarded for it.
This, more than anything else, is the problem.
