My main qualm is that I don't like bad stories - and BL mostly has awful stories. Flat, repetitive and, yes, tritely homophobic. But they got a lot of steam on several webcomic platforms over the years, so they are not going away (just like bad stories will haunt the webcomic world until the end of time). So, there is a market, Tapastic and other platforms aren't creative or brave enough to promote other comics, so they keep on pushing for what generates revenue, so that's the price we pay for it 
@Lindsette I am also a lesbian and I only know of maybe three comics other than mine that have good lesbian characters - not there to please your average straight porn fantasy/crazy/killed in the end/whathaveyou. If you know more, please do let me know!
