Republicans tend to be more intelligent then Democrats. According to studies, gay men tend to be more intelligent than straight men (I don't know about any studies of women). Therefore, it stands to reason that there are probably quite a few gay Republicans.
On the other hand, I've used such reasoning to prove that women cause brain damage...but not being gay, I wish that I was just a little smarter...
"gay men tend to be more intelligent than straight men"
Easily disproved. Straight men don't do something that gay men do, something that both know can kill you.
So, why does someone think that the person who makes the wrong choice is smarter than the person who chooses wisely?
