Looking for the failed assumptions and data errors in all beliefs is critical thinking

Critical thinking isn't just about challenging the official story. It's about subjecting all beliefs and information to critical analysis. And what you see on this site and read it, is people are more than willing to accept crap sources for things they want to believe while having exacting standards for things they don't believe.

Your failed logic is also pretty poor showing. To conclude as you did "in your world one cannot accept the mainstream story while being rational" is a wild extrapolation based on nothing but the shit that resides in your ego.

It's a direct result of your improper definition. If you altered your definition as I did above, then you have a pretty good one. As you stated it, your definition is incomplete and leads to this result.
