A fine example of slut shaming.
Far as I'm concerned, what happened seems to be a consensual sexual encounter. Why do you continue to disparage the woman? Yes, she's a porn star. So what?
Suppose that he had "ridden" a socialite and "put her away wet" (whatever that means). Would that be any more scandalous? In either case, his wife had recently given birth and he was dallying on the side, and it matters not one whit whether the person he dallied with was paid for pornography or was otherwise "respectable".
Far as I'm concerned, the dalliance doesn't matter much, though it certainly points to a kind of hypocrisy on the part of the "character matters" contingent of the religious right, who seem mighty willing to forgive their guy, but not those on the other side. Still, that said, Trump won't suffer much political loss from this issue -- unless the payoff ends up being a legal issue regarding use of campaign funds or an illegal campaign contribution.
The end result is this: the Republicans are losing their claim that character matters to them. It doesn't, if the character in question supports their policies. That's too bad, not only for the Republican party, but for our nation as a whole. All of us ought to care about character (yes, that includes the Democrats who ignored the issues surrounding Clinton).
Anyway, he's your guy (after Bernie, right?) and so no prob.
