And as for the non-denominational people....gosh, I know many and the reason they are non-denominational is because American families have done a lot of blending and some of the people I know feel that the non-denominational choice is LESS stringent and dramatic then Catholic, Lutheran, or whatever. People I know who are non-denominational or no more right-wing then I am. So, unless I completely misunderstand your post, I don't agree at all.
As if that makes me not a Christian.
Of course, the persons who come to mind right now are all members of a Presbyterian Church.
