Yes last year I was involved both in the local Courage group in Atlanta as well as the online Yahoo group.
I can tell you that there are many very kind and considerate guys there.
What I found though, is their remedy for homosexuality is one of complete self-denial. I can tell you many things but the biggest problem I have with them and the viewpoint of the Catholic Church is the proclomation that homosexuality is disordered and the cure for it is chastity. Any form of sexual expression (masturbation included) is prohibited.
I became good friends with a guy via the Yahoo Courage group and he too had the same tremendous internal struggle that I had while participating in the group. I can tell you honestly that since leaving them and accepting myself for who I am, I am at more peace. Not complete peace, but more peaceful, if that makes any sense.
Just my thoughts.
