I'll be honest, I tend to like Wonder Woman MORE when she's written like this, I just find it much more entertaining (much like the 'Out of my way, sperm bank!' characterization), but then I tend to go for characters that are difficult to get along with.

But it is so not proper Diana behavior. She honestly strikes me as the most accepting and least condescending member of the Trinity (I don't think Superman would intentionally condescend to anyone, but he still reads that way sometimes) and the most likely to support the Superbuddies (when they're not being totally irresponsible and ridiculous).* So yeah...Wonder Woman is a lot of things, but a bitch ain’t one of them.

*Though I’ll defer to one of the Wondy experts if my interpretation of her is totally off, I’m no expert. She could actually be a completely judgmental harpy and I just haven't read those stories
