Femmeslash fics are even worse at that. I'm a bi girl, I have a strong preference for women, and I'd love a major HP female character in a convincing pairing with another girl, but a lot of those fics confuse major depression with same sex attraction. I just want to read about smart and funny lesbians who explode shit and fight in a magical war. Instead I get stories that go like this:
Paris, Vienna, New York, and finally London. A cold October morning was painted in 256 shades of blue. A lone pigeon cried out in despair. Fleur was wearing a cardigan that fateful day. Hermione was reading a Jane Austen novel and pondering the nature of womanhood.
They then proceed to drink hot tea and stare into space for 48 hours, making no move to either have sex or at least attempt some magic.
