I don't necessarily disagree with what you have written, and it is certainly related to my question, but I think your rephrased version has digressed from the exact one I posed with particular attention given to New Atheism.
Using your example, have pro-active New Atheists played a significant role in the gay marriage debate so far? I'd argue that a far more substantial amount of support for gay marriage has come from the general public who do not actively criticize religion. Indeed, whilst I have no evidence to back this up, I'd suggest that a very significant proportion of those Christians surveyed that do not necessarily believe in a God, support gay marriage.
In short, the public seems more than capable of standing up for these principles by themselves without the need to criticize, aggravate and ridicule.
