I just wanna make a comment on this. Comics with the LGBTQIA+ label I actually don't mind, as they actually feel more like the tag is there to get readers from the said named community or readers who might be interested in it.
Something tagged with BL just sounds like bad porn, the labels has turned into click bait for fetish comics as that's what most of the ones I have read with that tag are (not all, there are some that are just fine, but then there are just REALLY horrible ones that are just there for the sake of filling a fetish that happens to be really popular)
To give examples when I was first trying to understand my sexuality make sense of myself I looked up BL (as that is what was recommended to me) it was a bad idea and a horrible experience, here are some following examples that for whatever reason, pop up a LOT when I was going through them.
I read a few BL where it was 'cute/funny' to jam an umbrella (or some other long large objects, whatever the author decided was cool I guess) causally up another guy's ass because 'heheh look at him blush, so cute, he's a uke'
I read a whole bunch where 'girls are evil rapists' yet the guys acted even more like rapists but THAT was ok'
There were a frightening amount of comics where literally all the woman in the world have been killed of (I duno, the reasons very usually it's a virus) so the guys are FORCED to fuck each other because they need to keep population numbers up and there is no one else to reproduce with. They aren't even gay (a lot of them like to bring it up, then they feel confused). They're FORCED to fuck other dudes because there are literally no woman left alive.
The rapists... why are there so many stalker rapists?
I read a comic where this one young boy was unsure about his sexuality and suspected that he might be gay. So what does his 'best friend' do to help him figure it out? Organize a gang rape.
That being said ^^^THIS is what the BL tag means to a lot of people. People are not bothered by it because it's a boy/boy relationship, most people here complaining about the BL titles can read comics that have male/male relations JUST FINE. That's not the issue. The issue is that they are bothered because the BL tag's been associated way too many times with fetish porn trash. It's no longer a tag that targets people in the gay community, it's a tag that targets yaoi and gay porn fetishist fans. (In fact, it technically NEVER was. IF you look it up you will learn that the title originated from Japan, 'Yaoi, also known as Boys' Love (BL), is a Japanese genre of fictional media focusing on romantic or sexual relationships between male characters, typically aimed at a female audience and usually created by female authors. It's not made for the LGBTQIA+ community. It's made for girls with a gay fetish.)
EDIT: Oh, ANOTHER really popular one, a comic where a guy is constantly getting raped, but they believe that they 'deserve it' for whatever reason, they are also addicted to it for some reason. They purposely go out and put themselves in situations were they will get raped because they want to punish themselves because they did something to 'deserve this' (usually the thing they did to deserve it is THEM BEING GAY... so yeah I can't see how a comic were the theme is the main character constantly punishing himself for being gay because it's wrong/unnatural/evil can possibly be aimed at the gay community)
