As a pansexual I feel that Bi and Pan have enough differences to both be justified while the others are micro labels (not invalid, just less useful as labels).

But I recognize I’m drawing that line very conveniently for myself.

Here’s an unpopular opinion: you don’t need any labels at all. You love who you live, you fuck who you fuck, you can advertise what you’re looking for if you want to but all this identity business obscures the reality that humans are far more diverse and interesting than the boxes we build for ourselves.

Most people who call themselves straight would fuck someone from their own gender if there weren’t cultural expectations against it hammered into them from and early age. Most people who call themselves gay would wander if they found someone they connected with. Very few of us rest at one end of any spectrum or matrix. Most of us are somewhere in the middle, and far more mobile than we might realize.

Atheism isn’t a religion, likewise asexuality is not a sexual orientation, but the lack of one, I say.

If we’re splitting hairs, bi should be a sunset of pan.

Also, there is some need for a fourth “none of the above” label…

Not understanding what words mean isn’t an unpopular opinion, you’re just wrong

Not about the first bit, that’s arguable

You definitely DO need more labels than straight, gay, and bi. For example: asexual or sapiosexual, those don’t fit into any of the 3 you listed
