Why would you? If you're a critical thinker who can exploit a knowledge advantage over the world, your life will get better faster than the life of non-critical thinkers, and they, in turn, will have their lives improve faster than that of a critical thinker fighting against the weight of non-critical-thinkers.

The optimal strategy for all people unable to determine if they're critical thinkers is to either go with the weight of opinion or to attempt to exploit their edge. The middle where you try to convince people is just free labour.
