Son, over half a dozen posters in this area have contributed their valued thoughts.
I'm still not buying "bi-sexual" is a sexual orientation, and in women it's not something that's generally frowned upon by most men (or women, probably). The PSA is to bring attention to gay, lesbian, and transgender rights...if anything, being a bi-sexual chick puts her at a HUGE advantage against the actually people the PSA is meant to help.
Alls I'm saying is, she's bad for their movement. Like a modern day Anne Heche.
