Why do " 4-chan" and those other dead beat Internet hang outs make fun of Michael J. Fox?

I don't know, these morons have come up with this whole " encyclopedia dramatica" page mocking Micheal j fox's illness. Making these stupid parkinsons jokes and these photoshopped pictures. For example: they'll have fox's picture next to " Haiti" rudely and stupidly imply that his Parkinson's caused the earth quake. I know they're just looking to push someones ons and I should probably just choose to ignore it, but it really does get under my skin. Why do they constantly bash the wonderful man?. I can't understand how anybody could stoop so, so low.
