I find the whole homo-ffection for Clinton absolutely bizarre to be honest.
For myself, I support the party that caters to my political outlook. That would be the Conservatives in the UK, and to a lesser extent the Republican Party in the US. There is not much more to it than that really. I'm not going to vote for a party/candidate that strongly supports gay rights but whom I disagree with on every other key issue. On the flip side, if someone was
rabidly anti-gay, then I wouldn't support that candidate either even if I agree with them on a significant number of issues. In my own experience there are a ton of gay Conservative supporters (although I probably would say that given my own social circle), there is also a lot of gay Republicans to be found on places such as Twitter too.
