What I am..(if you are too new to have known)... is a graduate in Philosophy. (134 hours and 1/3 of a Master's thesis). I never made a career out of it, but the basic lessons in what counts as logic and consistency have stayed with me..... and it can be scary. ;>0)
I can't read these discussions without wishing I could "train & supervise" all sorts of folks in basic logic..etc. Being aware of basic rules of argument would NOT mean that everyone would automatically agree on basic truth, morality and political correctness.... but it might avoid some of the most egregious errors in HOW to present & defend a position.
Some folks seem to exercise general 'reason' and fairness without resort to technical explanations... others never seem to. Why? Ask the psychologists.... who will give you answers that often only muddy the issue even more.

All this is why I type all these long, tedious attempts to make sense of an issue... I seldom have a clear, simple answer to the serious issues; I have MY opinions, and I have spent hours in the last 12-14 years on gun control, women's rights, political stances, 'fairness', language,... and arrrgghhh.. the "meaning of folk".

You may notice that disagreements seem to continue in spite of my inspired *grin* explanations....
