I stopped listening to the anti-Shep voices after the first go around. McKay is not a favorite for me, but I don't slam the character. So, I don't listen to them.

I got enough voices I either have to listen to or just ignore ;D

There are always those in any fandom. SG-1 has a major Carter bashing legion out there... Never understood why. Don't care.

Shep IS a guy, so is Rodney. You can't expect a man, any man, to be weirdly virtuous. And that's what it would be if any man didn't react to a woman.
