It makes sense, considering the self-professed "bisexuals" I've known, which are well known as well in liberal-leaning circles:
1. Young women who pretend to be Bi to get more attention from Men
2. People who pretend to be Bi to avoid having to completely come out of the closet
There's actually a saying in the gay community for the latter, "Bi now, gay later!"
To add on that, studies like the ones mentioned only reveal so much; there are a few good reasons why one might only search for one gender or the other online and in a particular place.
Some people only want romantic relationships with a partner of one sex while hookups with another. Some people have bi-cycles. Some people are attracted to a person of their own gender 80% of the time and another 20% of the time.
Many bi people aren't out or completely honesty with their dating history because they have to put up with the insecurities and stereotypes trotted out by the chronically ignorant from both straight and gay communities. The lack of support and understanding is one of the reasons why rates of depression and anxiety are higher for bisexual people. Imagine being questioned about your preferences and asked to make a choice by a group of people that were held to a similar level of cultural-interrogation by heterosexuals. Bisexuals are a minority of a minority, however, I am glad the attitude of thinking bisexuality is secretly indecisiveness is dying off.
What you're doing is called bi erasure. It happens from straight and gay people. Bi doesn't necessarily mean attraction or experience is exactly equally split. For some people it is, for some people it isn't. Some people may change how they self describe. None of that means people aren't legitimately bi.
My post was based on what I've been told by both Gay and Bi people (the latter, several Bi people I knew complained about the first item with the young women). So if Straight and Gay people can participate in Bi Erasure, so too can Bi people I suppose.
I think by gay community you meant asshole gay people, I've been waiting for a very long while now to turn gay (I'm a bisexual dude).
> I don't see how the bisexual statistic is politically incorrect.
Not politically incorrect, just deeply ignorant.
And as for the second, that may not be a conscious decision, right? People discover more about their own orientation over time.
There are plenty of acceptable ways to be bisexual, and while some people might fit the boxes you described, there are lots who don't.
These antiquated views are a large part of why, as a bisexual man, I mostly keep that to myself. Coming out is a big deal with a significant amount of associated emotional stress, doubly so when others try to rationalize how you're not a "real" bisexual ("you've only dated women, how can you be bi!?" or "oh you just like fooling around with dudes, you're not really bi" etc).
Then I fell in love with a woman, still happily monogamously married to after many years.
These days I would self identify as human. But I guess you could call me bi: I still find attractive men attractive.
I'm not sure what I would seek these days if I were single.
