It seems like the people you are having a difficult time with are increasingly unwilling to attempt to process verbal information that conflicts with their established patterns of thought and the noise that continues to reinforce those patterns.

You can see the exact same effect here too when a non-polically correct opinion is delivered.

Try suggesting that a 20% decline in petroleum production in five years -- to early 1990s levels for example -- might NOT cause collapse/depression/mass dieoff.

Heresy!

Admittedly, a 40%+ decline would be pretty interesting.
