I'm having a hard time reconciling that with the original statement that we need to do this "because homosexuality is a sin".

I'd say the same argument you're using for this could be used to rationalize virtually any exercise in federal social or cultural engineering.

Lots of things are sins, and you can’t legislate against all of them. Homosexuality is a grave sin, and with things like it along with murder and abortion, you can and should legislate against them.
