I think if you give others the benefit of the doubt when you reply, they tend to do the same for you. For example, I thought that JD's post unfortunately hit upon some archaic and scientifically unproven gender sterotpyes, but it was clear from the rest of his post that he is not a bigot, or even being disagreeable. Pointing out the weaknesses in people's arguments in a way that might be perceived as personal criticism makes people defensive. I think you make many insightful observations and comments. It would be a shame if you decided not to participate entirely on this topic.
