A specific post set me off and it's detailed at the bottom, but the short story is this: it CANNOT be appropriate for a rights advocacy movement to engage in deliberately harrassing behavior. Trying to screw with somebody's life, carreer, etc. IS harassment. That is "hate group" material. Mods need to be agressive about ensuring that MRAs do not cross the line into hateful and possibly illegal behavior.

The comment in question: http://www.reddit.com/r/MensRights/comments/s1gh5/an_open_letter_to_the_spermjacker_troll_from_a/c4alelc

tl;dr: Don't harrass people you disagree with. Don't call then. Don't publish their phone number. Don't call their workplace. Don't call their school.

Edit: this thread is meant to begin a discussion, but I firmly believe that such actions should not be condoned.
