Steve Shaw says: A proper conversation must start with the prior assumption that God does not exist.

Steve, could we level the playing field a bit? For the sake of fairness, I think we need to change one word in your proposition:

A proper conversation must start with the prior assumption that God MAY not exist.

Then, and only then, would discussion be possible.

As for your other question: So gay people will always be second class in the Catholic church then.
For the foreseeable future, I regret that's probably the case. I and others do what we can to promote a change in attitude toward homosexuality, but it's an uphill climb.
