It shouldn't offend men to have it pointed out that men represent a disproportionate amount of violent crime perpetrators. That is just a fact. On the other hand, a statement like, "Men are naturally violent" will get people's hackles up. (Don't believe me, look at any sexual abuse/harassment thread.)
The two statements are not the same. Regardless, the conversation has moved on. I commented because I get really tired of the sweeping, negative generalizations about Americans that get tossed around so freely on this board. In a heightened emotional state over the gun problem, I stumbled upon yet another one, and took grievous offense. It wasn't just that post - it was the cumulative effect of constantly seeing my country **** upon, combined with being in an emotional mood.
How people choose to carry on a dialogue is up to them. But there's nothing wrong with pointing out what I see as errors in their method.
