Doesn't really matter if Trump thinks grabbing whatever woman he wants, whenever he wants, is perfectly fine & legal. It's still assault even when the person is too dumb and/or deranged to see it. This is compounded by the numerous women that stepped forward and confirmed that behavior (even if some of them exaggerated or lied, it is doubtful all of them did, particularly with Trump himself boasting of such behavior - you'd expect there would be some aggrieved women out there)
I hate Trump as much as anybody, but he wasn't talking about regular women with this line, he was talking about gold diggers. Gold diggers don't care where you grab them.
I can't speak to the other accusations, he certainly seems like the type, but that line got WAY too much play....way more than the aggrieved women got. Which seems backwards to me.
