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?
