'Cept that as an atheist, maybe I hope y'all don't catch on too much

Please note I ain't got the graces of a goat, but I got me the curiosity of a cat.
Do the Jehovah's Witnesses vote their "religious beliefs" (as opposed to the normal stuff where ya just think it's a good way to go whether Jehovah says so or not)?...
Is there some sort of "Well me, Jehovah's Witness I am, I don't so much fret this notion of Jehovah's, as I'm willing to bend a bit, in hopes my goodwill might come back to me" (where such goodwill is itself right and good)?
Heck, I hate to come across as stupid, even if it's too late, but do y'all even vote? < On that, I am aware y'all were important in me not having to pledge me no goofy pledge to a nation that declares I trust in a God I can't even show exists. I sure 'preciate y'all for that'n, and I joined the Army sorta to help in all that.
On the blood transfusion deal, is there any leeway for a parent who's just horror stricken at the thought of their child dying, even if they're headin' to 'em a better place? If I'm a Jehovah's Witness in each and every other individual, mi-nute detail of my life, only I can't cotton to that'n, how's that work?
Is there something y'all need to say, that helps us to better understand y'all? Tell it.
