Yes, but just because it is certain religious scripture behind the denial of marriage for gays, doesn't automatically make it an atheist activism issue. You are assuming that to be against a certain religious scripture, you must be an atheist, or at least have atheist virtues. Nothing could be further from the truth.
There are many Christians who don't think the "anti-gay" parts of the Bible are true, or that they should be used to enforce laws. For something to be "atheist activism" I think it would have to involve atheists for an atheist cause. Gay Marriage isn't atheist activism (there are plenty of non-atheist gays); it's a gay rights issue...an equality issue.
Even if there are some atheists involved, there are far better instances of atheist activism.
