Actually, I should say that Catholics are the largest religious group in America and most support gay marriage being legal.
I know every place and person is different, but many Catholics I've talked with (more than fifty) throughout my time as a Catholic do not support gay marriage being legal. A lot of conservative Catholics don't support gay marriage.
Instead, they have this program:
Courage
"His Eminence, the late Terence Cardinal Cooke of New York, was aware of, and troubled by this situation. He knew that the individual dealing with same-sex attractions truly needed to experience the freedom of interior chastity and in that freedom find the steps necessary to living a fully Christian life in communion with God and others. He was concerned that many would not find this path and would be constantly trying to get their needs met in ways that ultimately do not satisfy the desires of the heart"
Supporting means accepting who LGBT people are and accepting their attractions, sexual identity, gender identity, without promoting the need to lead a life of chastity (unless that's what that LGBT person wants) or displacing that attractions and love are two different things.
Supporting is saying "we support and believe that you
are a woman (rather than a disordered person thinking that you are a female in a male's body). We see you as a female. We know you are a female. You
are a female. We accept this. We support you."
Unless the LGBT person feels he or she is disordered and needs help in not feeling separated from his or her own biological body or seeing themselves as having temptation attraction and needs support, if that is not the case, support should help the individual be who they are and understand who they are not how the Church defines them and how they should live their life.
It puts a barrier between that Catholic (some) and the Church when the Church (or god) says a person should be male when that person knows she is a female. I use transgender since that's a more concrete way to express my point since attraction is on a spectrum but not all transgender are LGB (going by my cousin who is transgender, straight, and in a beautiful marriage with a male).
I agree that Catholics (lay) are accepting and supportive of the LGBT community but not on that LGBT person's point of view. I don't feel supportive is the right word. Maybe accepting and welcoming that person as a person but I feel if you don't accept who I am as a person rather than tell me who I should be, that's not support.
But people are different. Not a debate, just saying that I don't understand how Catholic's can be supportive of a person when they don't agree with who that person is but define them as something else that that LGBT Catholic may not agree to in his or her heart.
