Where in the Bible anywhere is contraception mentioned? What are the "Apostolic" traditions about birth control and where are they found? Why is there NO pro-abortion plank in the Republican platform and why are Conservatives the ones who have ALWAYS rejected sex education, pro-homosexual orientation and birth control in schools? Why is it that Conservative Republicans have been the ones to fight against the legalization of abortion and gay marriage? You talk like America is mostly "Protestant" and Catholics are a minority yet we know that America today is made up of many religious and ethnic sorts. At one time America was said to be a "Christian" nation, but I've never heard of it called a Protestant one. It seems like you are piling on all the problems of the world on the backs of "Protestants" yet leave out that the ENTIRE world is heading for the toilet INCLUDING predominately Catholic countries (yeah, and actually CALLED that). Is Protestantism to blame for all that too?
Try some other way to divert attention from Christianity and the Scriptures and onto the "figures don't lie but liars figure" farm.
Try to come to grips with reality here. Genuine Christians - Catholic OR non-Catholic have within them a nature that rejects evil and by the power of the indwelling Holy Spirit we are capable of knowing right from wrong. On the other hand, there are numerous people that CLAIM to be Roman Catholic that are directly responsible for the degradation Liberalism has imprinted on our nation (i.e., Pelosi, Kerry, the Kennedys, et al).
All this foofaraw about "Core" again makes little sense as any kind of explanation for the trouble you seem to want to unload on all "Protestants". Daniel1212's statistics demonstrate over and over that when the heart is changed the outward life is also changed. Only a genuine faith response to Jesus Christ can make that happen. All the church-goin' in the world can't do it no matter what the sign says on the outside of the building.
Preach it, sister....
