What I don't understand is the pretense of defending Trump at all. I mean, it's clear that even if you watched Trump assault a 13 year old with your own eyes, it wouldn't impact your support for him. Why pretend that there is some moral divide between Bill Clinton and Donald Trump in this when you can just say "I support Donald Trump no matter what, and despite Bill Clinton no matter what"?
Personally I've never been shocked that some of the most powerful people in the world like to go to a private sex-island where they could do as they pleased. That's precisely the incentive to becoming so incredibly powerful in the first place: to be able to pursue personal gain with increasingly less consequences.
