So the thing you saw was saying that [by and large female] writers of slash are writing about men because they don't like/aren't interested in female characters, and that this is because society as a whole doesn't like female characters? Because yeah, that statement seems arguable with on several points.

There's probably lots and lots and LOTS of different reasons why people write slash. One thing I've thought is that for female heterosexual cis writers, it lets them explore relationships and sex and emotions without there being any implications for themselves--it's like it can be undiluted and more intense maybe? You write slash--what do you think?
