Let's face it, the majority of what American's learn is from TV. For example, Anna Paquin comes out as bisexual and then a hot minute later, marries her male co-star. Lady Gaga comes out as bisexual and dates a string of men. Madonna comes out as bisexual, dates a ton of men. This is where the perception that some are doing it for publicity comes from. I also think a part of the issue is a matter of "passing." That some LGBT people have issues with bisexuals because you can have that "normal" life we can't--in a sense, you can make that choice and it appears, many do.
Do I have biphobia? Probably, but I don't tend to think about it much because I'm full of phobias that I try and ignore or get rid of. However, the last two women I've dated were bisexual (I use were because one now claims she's straight--cause God intervened--and is married to a fundie preacher) and both women dated men after dating me--I hope one of them is happy.
