When you say the post is disingenuous, you are implying intent on the part of the poster. I don't see that (I don't disagree with your point that the characterization is inaccurate though).

How literal is your meaning when you say "Wow, that's pretty offensive, hate" below? Because I think hatred directed at a bigot is sort of a not very fruitful response to bigotry. In that sense, people being nasty because someone is saying offensive things isn't a huge improvement over people being nasty because someone is mentally ill.

I do see some need to deal with people that are being disruptive (whether intentionally or not), but I don't see much justification to do it with rancor.
