A) Mother Teresa
B) Adolf Hitler
Most would agree the answer is B. Then again, I could post your picture, since you claim to have been called a Nazi 1000 times in the last two weeks most would understand the point. :)
Hey, here's a wacky idea - how about if you don't post any comparative picture, and just go find evidence of that person doing bad things? That way, you can prove the point you're trying to make, that the person in question is a bad person, and you can do it with some modicum of intellectual integrity. I know, I know - you have to, like, work to make your case if you do it that way, and it's certainly harder than just making some sort of goofy off-the-wall smear by comparing that person to Hitler, but it really does the job, and it doesn't make you look like a nut in the process. Whaddaya say? Could be it's just crazy enough to work...
