You're insane. Please, please, seek therapy. You clearly have a brain but something terrible must have happened to you, and I'm sorry for that, but you need to find help.
You cannot equate "Would you marry an ex-child molester?" and "Would you marry someone who has had casual sex?"
Cannot.
CANNOT.
One raped a fucking child, dude. RAPED. A. CHILD. Another had a consensual relationship with another willing adult. You cannot and should not equate the two just because you happen to disagree with both. That is plain and outright creepy.
