The part that was interesting to me was the interview with his gay lab assistant who says the prof isn't homophobic. As for sample size, outside of bound it's probably difficult to get a bunch of guys to sit around watching gay porn with electrodes strapped to your genitals.

See, there will always be anti bi bias. Think of it like this, if you date a bisexual - you will either marry them or break up at some point. Now, when you're seeking reasons why it didn't work out, do you
a) think perhaps it wasn't meant to be in the long-run
b) admit you were a friggin twinkie
c) admit you had some fault that made them bad relationship material for them
d) realize they had some fault that made them bad relationship material for you
e) say ohmigod I fucking hate bisexuals they all suck

If you answered e, then you are part of hetero or homo sexual society that is responsible for sustaining the anti-bi bias. And yes, I do believe and hell personally practice the theory of bis dating bis - or at least not dating fuckwads that care about your sexuality outside of whether or not you want to boink them.

I think I'm going to paste this in Tony's LJ...he's ranting on the same thing.
