I think it is just a couple of individuals rather than a reflection of the entire group.

I believe that there is a massive problem with people not realising that there is an inherent difference between objective sexual orientation and subjective sexual identity. That people can identify as what they want regardless of inherent reality of what they are (political lesbians etc).

Other people here are scapegoating bisexuals for this and how this plays into the hands of the TRAs, but in reality this disconnect can hurt bisexuals just as much as Gays and Lesbians (i.e. gays falsely identifying as bisexuals making bi people look fake and in denial).
