I'm assuming that "bad writing" is too broad an answer, whether or not the more precise answer happens to fall within it. The obvious answer is a tendency (both in writing and among humanity in general) to latch onto figureheads/heroes and give them disproportionate amounts of praise and expectations. But that seems too obvious.

For the record, I'm defining feminism in a fairly broad "women should generally be treated equally to men, for the same reason that people should generally be treated as equal" sort of way. Not that men and women are completely identical or any other specific policies that you might or might not agree with. I know you have some concerns about gender politics, although I don't know what they are. (If the answer was a critique against "objectification of people in general", I'd consider feminism a subsidiary of that)
