When people bring up obvious exceptions to a argument.

Hate this about Reddit. Someone will say something like "Going to the gym and eating healthy makes you feel good!" and Redditors come out of the woodwork like "Well what about disabled people who can't work out?" or "Well I am allergic to vegetables and can't eat healthy."

a little dramatic but you get my point. It's so annoying. Just because you want to pick apart someones point doesn't invalidate the whole thing.
