I think most of us are tired of the "ther r no girls on the internetlol!!!" and "get back in the kitchn!!!!!!!" bullshit, of which these comments (although cruder) are in the same vein. I think that most of us have gone through immature periods of our lives (or even isolated incidents of immaturity) where we have made similar insensitive jokes. This is, unfortunately, exacerbated by the fact that this type of behavior is the status quo of many of the largest Internet communities. Although OCR is its own entity, we do not exist in a vacuum. People expect others on the Internet to behave a certain way (and receive comments a certain way as well). As D-Lux said, rather than banning them immediately, a warning should suffice for weeding out those who are willing to be civil and those who are not.
bonzai!, what was said to you was crass, offensive, and stupid, regardless of whether or not it was intended as any of these things. That said, I don't know that I would have interjected on your behalf (though I certainly wouldn't have spoken against you). For one, I do not frequently talk when I play TF2. Secondly, I try not to get involved in the arguments that do not involve me, especially on the Internet. And finally, responding to arguments like this in anger typically only fuels the fire. As I said, I do not have access to a complete account of what happened, but I hope that you will not assume that those who did not speak agreed with or supported what was said against you. Silence does not always mean consent.
