Don't lie to me, c'mon.

I'm not lying. I'm picking a well known person who isn't famous because of their art, but whose art is often shown on the Internet. I'll grant you that the art is often shown for shock value, but I'm not trying to "use him to disgust". I'm merely making the point that if you talk about how much "buzz" an artist's work gets, he's going to be right near the top.

Either, Hitler is talked about quite often, in which case, yeah, he's more significant than Picasso

Hitler is definitely discussed more often than Picasso. I'd even say that Hitler's art is discussed more often than Picasso's art. It may be for shock value, but again, if you're using "this person's art is talked about often" as an indicator for how relevant their art is, then he's going to be in the conversation.

Or, he isn't, because nobody gives a shit about his stupid castle paintings,

People don't give a shit about his castle paintings as paintings in themselves. That's the point I'm making. They're not talking about his art because his art is worth talking about. But they're talking about his art because of who he is. If what matters is how often an artist's art is discussed, then his art is important. I don't think it should be, but those are the rules that are being suggested.

People talk about him, they don't talk about his art

They talk about him and they talk about his art:

Hitler is very important: Sure. He is. Now what?

I dunno, you've decided he's important. Now I guess you go discuss his art? I'm having no part in it though.
