Why would they find that worth their time?

Agree and my own reaction took this a step further---I was glad to hear that JoeW, as someone who seems to affiliate with people politically opposed to PUA, got the impression that the PUA community felt no obligation to engage or respond. I would have thought less of the community if it did.

PUAs are not political activists. They are people who enjoy, practice and develop a specific set of skills with a specific purpose. Their comparative advantage really isn't in engaging in moral and political debate to convince others that they deserve respect, acceptance or special treatment. Moreover acting as if you need to justify yourself (or your group) to others already represents a significant loss of standing. That is one aspect of politics in general that PUAs should be expected to be familiar with, since it overlaps so much with the rules of the social game that they are dedicated to mastering.

(This is different from simply explaining their own personal ethical values completely divorced from any reference to external critics and in terms of conveying information rather than giving excuse. That is something that PUA-instructor types seem to enjoy doing.)
