It's the definition that (as I understand it) most pan and non-queer folk use. I'm pan, and it's the definition that I use. But many in the bi community will claim that bi means (and has always meant) that you're attracted to "your own gender and not your own gender." I recall once seeing a rather old source (from the '90s or possibly earlier) where this was explicitly stated, though I can't remember where I saw that.

But like, if that's all true, then the bi community has done the worst job marketing themselves, even within the queer community. I used to identify as bi. I had no idea. I always thought it was as you described, which is why I started describing myself as pan.

So to specifically answer your question, they typically argue that there is no difference and the term pansexual doesn't need to exist since bisexual already covers it. I don't agree, although I do like the colors of the bi flag much better.

If someone disagrees then they’re entitled to their opinion, even if those opinions are contradictory to the mainstream definitions.

Certainly not mean to tell people that their sexual orientations are wrong, is it? Do you think this is kind to be dismissive of people's sexual orientations when you state yourself that you are ignorant of it?

Jesus Christ.

You think I'm being a cunt? You haven't seen shit from me.

Is it mean to say I find it amusing that you're being real confident about the definition of something that you didn't know had a flag to represent it?

That was a light-hearted comment to be clear. This comment is not light-hearted though. Continue to use gendered slurs and you will be banned from this community.

Calling women "cunts" sure isn't a kind thing to do either and here we are.
