You are treating a handful of deliberately provocative online comments as if they were a reliable census of "lonely men" and asking whether it's okay to blanket dismiss all such men because of it.

In this case specifically, it's just more sexism from men for other men to laugh about. It doesn't matter the platform, real life or not. Sexism is always there.

1. Bots.
2. People can be vain.
3. People (not just men) tend to automatically acquit attractive people of wrongdoing. (Halo effect)

Jensen Huang is a horrible person who deserves prison.

Now, with that out of the way, Tech Bro appears to be satire and furthermore I don't think the moral implications have anything to do with the fact that many if not most men would cheat in that situation as a matter of fighting against instincts and the average person being a selfish moron.

"explain to me why should I ever feel empathy"

You can just stop there. You've already said everything that needs to be said.

All I'm reading from you ist "But I want to be A misandrist!"

Consider that the posts and comments might be from propaganda farms deliberately trying to sow division and loneliness. We are all being manipulated on a unprecedented scale. Some men you meet might have those beliefs, and once your aware of them, run. Some are just poorly socialised men.

All that said, I would hate to be a woman dating these days, collectively, men are pretty terrible.

That's not Alice Huang

Because you're applying a statement from one guy to all men, doesn't sound like a fair opinion to me.

Actually, I am from silicon value, and I’ve rubbed elbows with the Huangs on several occasions. Once I started chatting with Mrs. Huang in a line at the buffet, turns out she is an extremely witty, charming person, engaged in many interesting projects. She also runs her own business, but is mostly socially active. We discovered that we both share the same hobby (extreme ironing). Weirdly enough, she referred to Jensen as “the hand puppet”.

His wife is not ugly wtf?

Honeypot spy has knockers next to her knees.

Some people have no morals and in the current Western climate, it's okay to flaunt one's lack of ethical standards and heart because that's what powerful people do. Disregard them, like God will disregard them on the Day if they continue this way.
