do i think that a potential partner would be a little more willing to take the kid to church on request? what would i think about that?
frankly, when i imagine these scenarios, i always assume i'm a single parent. the reality is that i have no desire to have children, whatsoever, and don't expect i ever will.
i wouldn't expect i'd get to the point of adopting a child with a partner unless we were compatible on this. so, the right answer from my perspective is that i wouldn't raise a child with somebody that would be interested in taking it to a religious service on request; if i ever got there, it's a fair assumption that there would be no daylight between myself and the person i'm coparenting with.
that said, it's the kind of thing that may lead me to walk out on somebody, not because of the kids, but because i'd lose a lot of respect for the person. i couldn't imagine looking somebody in the eye and trying to be affectionate with them when i know they were at church a few hours ago. it would be a relationship-ending decision, because i'd just get up and walk away.
but, whatever the outcome, i would realize it's not my place to tell people what to do or what to think, even if i choose to avoid them in the future, as a consequence of their belief system.
