You didn't say some women benefited from privilege; you said that ALL women MPs were there because of privilege, not on their merits. That's profoundly disrespectful of their skills and efforts.

I'd be interested to see some examples to back up your claim that it's unacceptable to say that women are privileged: I fully acknowledge my privilege as a wealthy, apparently straight woman of the dominant culture, and, mutatis mutandis, so do all the feminists I know, on and off LJ.
