I don't think your post is accurate. I really don't believe that all of Trump supporters don't care if he rapes 13 year olds...I'm like the doubting Thomas on this issue if it involves Trump or republicans. If I'm a 13year old, raped by a US billionaire President, I'd be suing for multi multi millions, no matter what settlement I might have agreed to before. And that hasn't happened...
At the same time, I don't think anyone should just discount the claims off hand. If we have the files, then we should be able to find out who this person is. Somebody, be it the FBI, or a Congressional investigation team - not some semi staged hearing but an actual investigation - should be charged with doing a complete investigation.
No matter what your political affiliation, it is not OK to have sex with a 13 year old.
