First of all I just want to say I appreciate your effort in typing all of this :)

Second, yes I am indeed talking about BL and not yaoi.

Third, if you want to talk about yaoi, I get that these male artists presented homosexual art first before the wave of female artists emerged in the late 1970s. But is that "homosexual art" already yaoi? The term was created because of this new wave of attention. Yes they may be the inspiration, but not the origin.

Anyway I have better things to do than fight over this. Our (me and other replies and downvoters too) point is really just you're being too rude about OP's wholesome discussion and being all almighty about a genre that doesn't belong to anyone.

Cheers :)
