You seem desperately to want to believe that wikipedia can be what it claims to be - neutral.
In spite of your attempts to explain away the obvious liberal bias that appears in almost every article that touches on controversy, the bias remains.
That ought to bother anyone who truly seeks neutrality. I hope it bothers you and that you will bend over backwards to root out the problem wherever you see it on wikipedia.
Status quo: wikipedia has an obvious leftward bent
Its up to people like you (who appear to be respected editors at wikipedia and who also appear to truly want wikipedia to be neutral) to ensure editors that try to provide balance are given wide berth and support as they wade into the wikipedia water to improve its content.
Is there any room in your thinking for genuine disagreement?
