I totally get where you're coming from, and I think it's important to keep in mind that these mangas are made in Japan, where the culture is very different. LGBT still isn't widely accepted, and I'm pretty sure it isn't "basic common knowledge" for them because it's very shameful to like someone of the same gender there. I'm not saying I support that part of their culture, but the media of a culture will only reflect the culture itself, so if you want more acknowledgement of LGBT things, you won't find it in a form of media written by someone from a homophobic and predominantly ignorant about LGBT culture.

Is starting to be a pain in the ass when every damn manga takes the B in LGBT as, i don't know, I'll say BLIND 'cause bisexual people are invisible to them or something.
Every time a het guy on these type of mangas falls in love with another man says something in the line of " well I like women but I just fell in love with you 'cause you know it's you" what kind of bullshit is that? you can be new on the collective and be discovering yourself, but i think things like knowing what stands on each letter of LGBT is basic common knowledge, and it kinda gives the feel of hollowness on a character when he doesn't try to understand what's going on in his own mind and just goes with the flow 'cause it doesn't feel wrong to him.
Yet again, this is just a typical cliche BL manga for a sweet time reading, so I'll probably shouldn't be calling the shots here, my bad
