I have yet to meet a woman who doesn't love to talk about relationships with other women. Hers, her friends, a celebrity, whatever. It's by far the most popular subject. And while men may not talk about relationships per se, we do talk about women. A lot. In fact, there's a convincing argument to be made that everything we do is in the pursuit of securing or keeping a mate, so it's not so strange that we would talk about it, male or female. (Replace opposite sex with same sex as applicable -- this is not a hetrosexual phenomenon.)
Cartoonists are good at getting a laugh (hopefully), and on the surface this is something that people may not have noticed before it was pointed out, but that doesn't mean it's a bad thing. It's funny that we drive on a parkway and park on a driveway, but do we need to resolve that by rewriting our dictionaries? Probably not.
The insulting thing about the "Bechtel test" is actually that it diminishes the importance of these conversations. There is certainly a place for women in all areas of society, but insulting what many find to be the most important to them is not the way to encourage that. You don't have to shit on the volunteer fire department to encourage people to feed the homeless. We can applaud some portrayals without mocking others.
