Viewing everything skeptically causes one to doubt things that are true, and also to doubt that things that are false are really false. That results in undermining the truth and reinforcing the lie. Everything becomes an undifferentiated "shrug?" and important beliefs stop feeling as if they're worth defending.

But it turns out that most of us want to have strong beliefs after all. So, after our commitment to democratic principles (along with everything else) has been weakened due to the skeptical paradigm, we are ripe to have other strong beliefs take the place of those which have been dethroned. Enter fascism, evangelism, and other belief systems with highly dedicated cadres. They're like opportunistic infections which take root when our natural bullshit-detecting immune systems have been destroyed by a diet of excess skepticism.
