What type of genres are you reading? Are you reading male and female authors with male and female main characters in the same genre? It's not fair to say Clive Cussler's books are filled with confident & adventurous characters, but Edith Wharton only wrote only miserable, whiny, rich women, therefore men write fun characters I can relate with while women write about a bunch of boring drips. Make sure you're giving fair play to the writers and characters.

Also, I'd recommend staying away from "female empowerment" books if you're feeling this way because they will only solidify your bias. Those are the one genre, I, as a woman can not relate to at all. The broad generalizations, sweeping judgements, and useless affirmations do nothing for me because women are INDIVIDUALS with different life experiences, struggles, triumphs, personalities, etc. We can't just be put into one box, told what our problems are, and then given non-specific platitudes to solve them.
