The word "gay" means different things depending on how it is used. It may refer to someone who practices and/or advocates homosexual activity, or it may mean someone with a homosexual orientation. The two are not unrelated but they refer to very different things, with significant halachic differences.
It's obvious that an Orthodox Jew cannot favor something clearly forbidden by halacha without being oxymoronic. It's also clear someone predisposed to do something forbidden but wants support to do the right thing deserves it. In between there are perhaps grey areas which hopefully can be judged by a skilled and sensitive posek.
