Actually I may not agree with your politics but I agree the tradtion of self-criticism is very lively and very vital, very western...and endangered by many of the factors you mentioned.
Whatever you may say about Americans, I have yet to see another country with so many people that openly and unstingingly bring up its bad aspects on
line. Yes, the interent is full of chest-thumping American chauvanism but it is also filled with reams of self-criticism, hand-wringing, and
preditictions of doom.
If this lively tradition of self-criticism truly declines further, the west is in for dark days indeed.
