Freedom Fighters...though a bit misguided.
The fact that they stay put in a party where they often tend to be unwelcome is a gutsy decision, however they are not agenda setters and could probably have more influence if they were members of the Democratic Party. Having said that I do support them in principle and that they are truer to traditions of the Republican Party that the evangelist intelligent design nutters are.
I do think you are being overly harsh on the Republican Party, afleitch. You are assuming it's nothing but gay-hating fundamentalists, but that is no different than assuming that Michael Moore represents the whole Democratic Party.
I would pay gay people the respect of thinking that they're really no different than the rest of us when it comes to the major issues like taxes, economics, crime, foreign policy, etc. Therefore, if they find Republican views on these issues more compatible with their own views than those of the Democratic Party, there is no reason they should not be in the Republican Party.
