Political discussion in a nutshell. It's always possible to find some idiot who happens to belong to group X and holds opinion Y, and then use that to tar the rest of the group.

I can picture a perfect Improv Everywhere scene: a bunch of people get together and practice/research statements that make them sound like they hold awful opinion Y. Then, they sneak into a political debate, or a protest that has a counter-protest... on both sides. And then they all simultaneously try to call the other group out [with the other people they came with as their specific examples] for having opinion Y.
