Ok, please don't kill me, but I don't think there was any reason to escalate that thread quite so much over criticism of a single bad joke.
Yes, it touches on real-world issues that are very serious and the commentary on just how very real-world and serious those issues are is correct. However, humor is how some people actually deal with these things, instead of exploding with rage every time they are reminded about them. Political incorrectness is an incredibly common form of humor and generally acceptable to most people, so long as politically incorrect statements are made to an extreme that can be easily recognized as insincere. I very much doubt the person who made the comment about "sending Toady a female" was serious about it.
Yes, it should be no surprise that if pressed on the issue, people will reveal that they actually have bigoted perspectives, though it's not clear at all that they're so bigoted as to actually believe that a joking statement would still be acceptable if made in sincerity. Regardless, you guys know better than anybody how big the problem is, and shouldn't be so surprised when you successfully out some people as holding sexist viewpoints.
I tend to avoid doing this online, but in real life, I make sexist/racist jokes on occassion. I grew up in a community where such jokes were made in sincerity all the time and I found it despicable. One of my forms of retaliation today is taking those same jokes and dialing them up a notch, and it becomes instead a joke at the expense of bigotry rather than in support of it. The black and female friends I have welcome it, and actually engage in this sort of humor even more often than I do. Yeah, it's debatable just how much this instance is in alignment with this excuse, and I understand the activistic urge to fight for one's cause on every sighting... but you're not going to gain any ground by damning swaths of people over a distasteful remark made in jest.
I understand I'm in the minority here. Will commit seppuku if deemed necessary by the community.
