Uhg, I HATE this. I've seen men yell at men about how men aren't allowed to have opinions on this issue. And when I or some other female asks, "Well, then why do you care? Why do YOU have an opinion?" He answers something like, "I don't, this is my wife's/girlfriend's opinion, and those men are undermining and demeaning it!" My fist thought is "ew, way to show some balls", my second thought is "well, how do you know they aren't defending their wife's and girlfriend's opinions?" But I've never said either outloud, it would have been wasted breath.
