There's nothing wrong with the logic of "they were asking for it" in some contexts. Rape, violence, etc. of course not, but I think when it comes to being insulted, saying that someone was asking for it is fair. I've been attacked verbally before, and often I was asking for it or deserving of it.

That said, I don't think this is a case of her asking for it. It's just pointing out hypocrisy, which is a perfectly OK thing to do. It's less extreme but analogous to pointing out someone who complains about domestic violence being themselves an abuser.
