What's the deal here?

I didn't want to make this post but it's something that's been really irritating me lately. I've seen a large number of posts by women here talking about how they hate when guys play games with them. I've read post after post about how unfair women feel it is and how hard it is for them to find a guy who won't just try to manipulate them. I even read a blog about the technique of negging and another about a woman's issues with date doctors. 
HOWEVER, I don't understand why people seem to ignore that women have their own date doctors and have had their books detailing male psychology for years. Years longer than men have had their formal teachers. There's an advertisement on this very site for crying out loud linking to one of these women detailing "the secret psychology that makes him fall in love and keeps him hooked for the long term."

Now, this sounds a lot like the terminology that the dating doctors use quite regularly and sounds like what was once known as a man trap to me. 
As some of you may know, I was raised by two women. I've been raised to believe in chivalry and honor from a young age. I was taught to respect women and value them as equals. I've counseled numerous women and I'm well aware of the heartbreak that women can suffer and I'm sympathetic to it. I know this is a difficult game. This is why I have no problem with either side stacking the deck in their favor and learning about the other side. I do, however, have a problem with double standards. People are entitled to their opinions, but what is with the hypocrisy? Women, why is it that you criticize men for something and then ignore it when your own gender does the EXACT SAME THING?! If you have a problem with men learning dating techniques and psychology, how is this any less deplorable? Why is this particular aspect not condemned as well? How is this any different?
All I'm saying here, is that if you're willing to call out men for a behavior shouldn't you be willing to do the same thing for your own?
