Hate is a very strong feeling. The threshold for hating a co-human should be quite high. Most people "hating" Musk have not met him and have not been assaulted, wronged or harmed by him, and he has only had minor impact on their lives (depending on how much credit you give him personally for products such as Tesla)

I find it difficult to understand the level of aggressiveness he awakes in some people. Are they actually feeling hate or just camouflaging some other feelings? Envy? Injustice? Are they hating him on the behalf of others?

I hate anyone who lies as much as Musk does.

He's mostly not lying, he's just delusionally optimistic.

It is.

By definition. (Look up what "hate" means and what "rational" vs. "irrational" mean).

It is just as irrational to love him.

I hate anyone who lies as much as Musk does.

It really is. There are thousands of more hateable public figures who have done far less good and far more bad who get only a tiny fraction of the hate I see on hackernews and reddit. Heck, pick a billionaire that's not Bill Gates...

Musk has an actual hatedom of people who try and downplay every good thing he's done and every good trait he has while spreading bad rumours about him, both well founded (impulsive, stubborn, optimistic to delusional levels and not good with peoples feelings) and not (Musk knows nothing about rockets, paypal money came entirely from superrich daddy's slave labour emerald mines and no one wanted the mini submarine).
