"Maybe I wouldn't feel this way if I hadn't agreed with every last nasty word of it..."

You agreed with every last nasty word of it, and the sexist frame in which it was presented.

On the one hand, the sexist frames you and many of the other XX-factor bloggers employed in your coverage is a poignant, if somewhat startling example of the manner in which (apparently) unconscious misogyny rampant in our culture is internalized by even the women who inhabit it; once swallowed, undigested, you'll perpetually regurgitate those memes until you have the courage to examine them.

On the other hand, the apparent invisibility of the inherently sexist nature of the memes you promulgated, (and still promulgate, I guess), to yourself and such a large proportion of the population, is a depressing reminder of the intractable nature of prejudice (and, perhaps, the duality of self-loathing and externalized disgust).

I hope the repetitive broadcasting of your beliefs doesn't prove too much an impediment to figuring it all out. [Hint: it's long past time to stop digging, because the hole only gets (even) deeper from here.]
