I'm assuming your irritation at feminists was somehow a result of reading that quote. I'm not sure how that quote makes you think "oh noes, identity politics".

Explain yourself.

Also, why shouldn't you be implicated as culpable in the oppression of people? You, and I for that matter, both live the comfortable lives that we do in large part because of the oppression of large parts of the rest of the world, both historically and in the present. What gives us the right to benefit from that but at the same time say we aren't culpable in any way?
