My take is that not many people hate Elon Musk. Some or many people may dislike Elon Musk. For example, I do dislike Elon Musk. But, I do not hate Elon Musk.
Well, let me put it even better and in a more accurate way (which extremely few people would understand) : I do not even dislike Elon Musk, because as a person, (in public) he is quite pleasant and friendly. I may dislike some decisions that Elon Musk takes, if those are decisions that may negatively affect some or many people. Hatred is a very strong word that nowadays needs to be used after due thought. People need to (especially nowadays) understand that there is a difference between hatred and dislike.
Example : In the cola category of beverages, I drink Coca Cola and not Pepsi. I dislike Pepsi, because I feel it is overly sweet and lacks a proper cola taste. But, I do not hate Pepsi, I dislike it.
You can dislike something or someone and yet not hate that something or someone. But, if you hate that something or someone, then obviously it also means that you dislike that something or someone.
Not liking something or someone, does not necessarily mean hatred.
