>19-year-old women and 45-year-old men are adults free to decide to do what they want. If they choose to do something you disagree with, others disagree with what you do.
The president was actively betraying the trust of his wife and family, so in fact it wasn't as libertarian as you make it seem.
Beyond that, the memoir clearly shows massively inappropriate behavior for a sitting president or anyone with such a power disparity, to include significant instances of coercion and actions which denigrate the position and shame the relationship he had with his wife.
That may be so, but the problem with that avenue is that often people think they've made a logical argument when it is full of value judgements. In this case the comment in question was full of value judgements and assumptions based on incomplete information (they may be true, but they may also not be), and the final appeal to emotion was nothing more than a strong emotional restatement of an argument that did not rest on logic to begin with.
If an argument doesn't resonate with you it's easy to simply say I respond to reason rather than emotion, or vise versa. Or point out the problems as you just did, perfectly fine approach, but you can't ban emotional arguments because sadly, most people are emotional, and those arguments tend to work better. It'd be nice if everyone only responded to non fallacious logical arguments, but it just isn't so.
Sure, emotional arguments are a vessel to deliver rational, logical conclusions to those who are not persuaded by logic itself. But rational conclusions and analysis come first.
The reason I state that is because the OP glosses over the positions and power dynamics at play, turning the prime actors into just two regular old people.
Context matters and purposefully taking it out to make a point about moral relativism is disingenuous in my opinion.

Shame on you for equivocating.
