Why labels ?

I really want to understand, I truly do. I get the LGBT part, but now there's a lot more ancrynoms(?) added to it and I'm so confused. For example Demisexual is only being sexually attracted to someone you have a deep connection with first, but why label it as an actual word like Demisexual? Why not "I just don't feel attracted to anyone I don't have a strong connection with" why have all these labels for things that are just preferences. Yes, I understand 100% that this sounds ignorant, because I am ignorant when it comes to this, but I want to understand.
(P.S I'm not trying to be offensive in any way, I truly want to understand)
