If you don't mind me asking, why do you hate Dali? (I don't really know much about him, so I'm sorry in advance if he did something really horrible I just don't know about)

This may be a long answer but let me clarify first, you don’t have to apologize for not knowing something. 

Now let’s dive into my seething hatred of Dali (note: not all offenses are on this list are on the same level, it ranges from supporting Hitler to just being a jerk):

• He supported Hitler, in fact a surrealist group kicked him our for this saying that he was removed because of: 

  “counter-revolutionary activity involving the celebration of fascism under Hitler.”

• When he was a child he threw his friend off of a bridge.
• He didn’t pay his secretaries. He gave them commissions instead, and while it worked out because they sold them after he got famous imagine what would have happened if he hadn’t.
• Again, he was really into Hitler, saying “Hitler turned me on in the highest…His [Hitler’s] fat back, especially when I saw him appear in the uniform with the Sam Browne belt and shoulder straps that tightly held in his flesh, aroused in me a delicious gustatory thrill originating in the mouth and affording me a Wagnerian ecstasy.”
• He beat his wife

There are a lot more things that bother me but these are the headliners. I may write an article about this man one day, but honestly every time I try I get so mad my hands shake. And I think George Orwell said it best:

“If Shakespeare returned to the Earth tomorrow, and if it were found that his favourite recreation was raping little girls in railway carriages, we should not tell him to go ahead with it on the ground that he might write another King Lear …  One ought to be able to hold in one’s head simultaneously the two facts that Dali is a good draughtsman and a disgusting human being.”
