Again, it's not about that. Call yourself what you want and correct people if they get you wrong. In turn, acknowledge and respect the reality that the vast majority of people, LGBT or not, as well as every dictionary under the sun define gay as being attracted to people of the same sex or gender and use it accordingly. This is also unlikely to change since the (abominable) word 'queer' already covers all the bases you mentioned.
Can't believe I have to point out that straight and bi people might not like being called gay to someone on Dynasty tbh. Imagine the reverse...
