Get real, bud.
He has made a bunch of comments on her body. He was perfectly fine with Stern calling her a "piece of ass" and discussed her breasts. What kind of father does that?
Do you have kids? A daughter? If so, would you be comfortable discussing her body with other men?
I don't have kids but I imagine I'd be disgusted. Those are straight up fighting words. I know Stern is a shock jock, but if some old dude started talking to me about my [hypothetical] daughter's breasts, I'd be disgusted, enraged, and likely to hit him. I wouldn't entertain the conversation. What kind of father would?
As far as Ivanka defending him, she actually said she found the comments "disgusting", and that she was bothered by it until the stories were "discredited". But they weren't discredited. They're on tape.
The way he has commented on his daughter's body and saying "if Ivanka weren't daughter, perhaps I would be dating her" is creepy as fuck. Fathers don't talk about their daughters that way. It's disgusting behavior.
It's wild how people can take emails out of context about walnut sauce and pasta, but completely shrug off Trump's comments. About his daughter, about women, about teen beauty pageant contestants.
