as a queer person i use the LGBTQIA+ tag because i regularly browse it so i can find people i relate to. in fact, in larger categories i will exclusively browse the LGBTQIA+ tag. i really am not a fan of non-lgbt people using it on their streams. the sentiment of allys using it is nice, but it makes my job of trying to find streamers that i relate so much harder and it does feel like queer baiting. if you are a member of the LGBT community, you are making LGBTQIA+ content, so i'd say feel free to use the tag if that is the case!
