I agree that bisexuality is easily dismissed. Most people, straight or gay, typically acknowledge a person's sexuality with higher regard if the person has "picked a lane". For myself personally, I don't view myself have bisexual. I don't particularly court someone based on which gender I feel attracted to at the moment, I am more attracted to personalities than I am to biological factors such as what's between someone's legs. And I feel like that's a valid stance to have.
I'm not a bad driver. I just drive drive better at an altitude of 3,500 feet where I'm not surrounded by morons.
