At least in part.
I believe that a lot of people who say that they don't hate gays, but will admit to being uncomfortable around them, really are homophobic but won't admit it to themselves. Not all. But enough that I'd guess that over 50% of the population is homophobic.
Note that I consider you homophobic if you claim to love gays but think that it is wrong to allow them to have gay sex. Which the position that many evangelicals take.
Cheers,
Ben
