I just don't see the point of getting them to be on our side. I figure my generation, with almost none of my personal peers (about 800 or so spread over a wide geographic region, encompassing almost all of the US) being religious(maybe 2% actually practice, 20% tentatively believe, the rest are atheists), will wrap this up in time without the need for religion's support and acceptance.
good riddance to it anyway. It's caused enough harm.
