There are a few issues the Gay people represent, and they are often mushed together.
1) A male being attracted to other men: There is a Machloikes in the later Achronim as to whether one can be born with this attraction or not. This is also a fierce debate in the scientific world.
Whatever the case is, Judaism respects that different people have different nisyoinos. We do not ostracize somebody because of the tests HKB”H sends him. We must support these people and not make them feel guilty for having the nisoyon – and where possibly, try to end that Nisoyon with whatever means we have at our disposal (eg therapy).
2) Marriage or relationships: This is what we refer to as a Toievah. People who are involved in such relationships must not be encouraged or legitimized in any way. No religious party should be saying anything in support of such people.
