If the 'organized religion' of the 'religious right' is about control, tell me whose control? Aside from Catholics, most of those on the 'religious right' - myself included - that I know go to their own church which is either independent from or only loosely affiliated with some sort of national or widespread organization.
Secondly, I would repeat my question which you didn't answer. Why would anybody desire to know the position in which anybody and their spouse had sex? Are these 'religious rightwingers' just totally irrational beings that seek to arbitrarily embarrass and condemn the private actions of others?
And if history really proves you right and right again, I truly must be, as you put it, 'grossly misinformed'. Up until now, I was unaware of any historical examples where Christianity has cared one way or the other which sex position a married couple used. But I suppose a person of your infinite intelligence and wisdom doesn't need history textbooks and research to provide these examples -- they can be deduced through pure logic!
