Regarding abstract thinking: I went to a seminar once where one of the presenters, an PhD, said that he is naturally a concrete thinker, but that through the use of multiple tools has helped himself be able to think more abstractly. I have noticed in my practice it is people who have gone to Sunday school who are the abstract thinkers. They have been taught the Christian 'parables' and what they mean. So they can apply that skill in other area.
I don't know about that as I have found conservatives in general are good at concrete, abstract, objective, and subjective thinking; however it is well known that many conservatives are also Christians so maybe Sunday school does have a bearing on it. However, I know many Christians who are passionate liberals and, though they grew up in Sunday School, still don't do well with abstract analysis and won't consider anything concrete or objective apart from how they
feel about it including what is and is not politiically correct.
Example: We aren't supposed to consider any downside or long term ramifications to illegal immigration but a true Christian attitude is to understand that the people coming across the border are simply wanting a better life for themselves and their families and they are God's children too and we should accept and love them and make room for them. Discussion of the downside for the illegals is not acceptable and must be shouted down, yadda yadda.
I know many conservatives, however, who are agnostic or Atheist and didn't grow up in Bible class who are able to avoid the fuzzy feeling syndrone and see the whole big picture. For that reason I don't know if we can give Bible stories the credit.

(But then I think I can reason abstract principles, lol.)
Anyhow, extrapolating that to this incredible Zimmerman trial, we should have known what was coming when the initial leftist media reports defined Zimmerman as a "white Hispanic." Have you EVER seen such a designation used on anybody before? Ever? That told you from the get go that he would be branded guilty and Trayvon Martin as the innocent victim of racism. There didn't have to be a shred of proof about that. In the liberal world that is the scenario that 'feels' right and therefore it must be made true.
