Adverse effects of religious teaching

Unlike PZ Myers who has written often and militantly against deist teaching, I had primarily held a neutral stance, thinking religiosity was relatively harmless. Then the recent presidential election occurred and an editorial at Truthout blamed it on irrational thinking... so putting it all together...

Religion imbues irrational thinking because it promotes belief in beings which cannot be detected by any physical means. It teaches followers to believe in things they cannot rationally sense.

Abrogation of rational thinking through early religious indoctrination sensitizes followers to further irrational and illogical arguments.

Propaganda and marketing uses emotional appeals to shortchange/ short circuit rational and thus critical thinking.

While both Republican and Democratic parties are guilty of propagandish tactics and arguments, the recent president-elect was particularly adept.

The problem is that religious teaching and practice is legally protected by the US Constitution. How do we get around that obstacle?

Update: Confirmation that religious teaching is anti-critical thinking - NPR reports Evangelicals don't trust scientists.
