Ok, there is no absolutes, but look at the odds.
The weakness in my case of course is that not all Happy (gay) people are Liberals, other than the drug users in that crowd, I find it amazing than any liberal could actually be gay.
Ok, I know the OP was misusing the word "gay" and was actually referring to Homosexuals, so what percentage of homosexuals are liberals vs non-liberals.
What percentage of atheist are not liberals?
What percentage of blacks are not liberals?
What percentage of Women are not liberals?
Also, it is not liberal or socialist, liberals are a class of socialist.
So, while possible, the odds simply say that there is very little probability of a homosexual black atheist woman existing. I simply play the odds. Add that all politicians are liers, I simple would never believe that a homosexual black atheist woman was not liberal, despite what she might say.
