Agreed, completely. But it seems like human nature to do so.
The ironic part is you kind of just did so, by labeling it human nature
If you think about it, it's less nature and more of what people are raised to believe. Many things that we attribute to human nature is more environment than nature.
I too have seen bisexual men AND women get pretty negative treatment. I think it's less known for the sheer fact that the negative feelings and treatment towards the Bisexual community is less....overt in the grand sense like media coverage and such than the other parts of GLBT. It doesn't make it any less there, or any less painful and difficult it's just less thrown out into the open with all of the fanfare and dragging feet as the rest of the acronym.
Also I will have to throw my hat in with the fact that sexuality isn't just a statue that stands the test of time, never wearing and never moving and blah blah blah. It really is fluid, and the liquid metaphor is quite a good one as you go on in life I've found that not only can the current change, but you find a few things in those depths sometimes
. For instance I've noticed quite a few new things since having joined Elliquiy and having been around some of my new friends that I wouldn't have really given thought of before. Not too mention I'm starting to wonder about my actual orientation (if that's even the right word to use anymore >.>) in and of itself. (le gasp, the male may not be all for me? O_O xD)
Odd thing is that I have never disbelieved in bisexuals....not that I don't give my Bi friends a hard time sometimes.
No really, the one really is greedy....not gonna sugarcoat that one.....
