"What's the worst argument you can think of?"

Since you asked... Some people told me I shouldn't be vegetarian because I kill plants.

And my reaction to such arguments is the surprise of learning that the human mind really is that broken. I used to be under the impression that as intelligence rises, the ability to spot certain fallacies should be reached before the ability to ride the long bus.

I don't feel any pain, but sometimes I feel like I'm SUPPOSED to get an ice cream headache from the overwhelming stupidity.
