You know what. I think I have more of a problem with what we consider traditional "yaoi" (the Japanese thing) rather than with BL. You know, heterosexual woman making a very sexualized story between two men where there is a lot of emotional abuse and blackmailing, where the sex scenes generally include fetishism (nothing against fetishism, but God knows that needs a lot of discussion between two partners before attempting it) and often rape.
And where you end up wondering why the author has to make it so cruel and graphic. Is it some fantasy (nothing wrong with fantasies) of hers that she is too fearful to transpose onto a female-male relationship because people will think she is projecting (is it me or is there way more sexual abuse portrayed in yaoi than there is in manga showcasing heterosexual relationships)?
I actually like the BL on here. Often it is closer to the reality of how relationships work (whether there are feelings involved or not).
