SFT #1: On Mental Illness & Climate Change.
I find a less recognized way in which religion harms society is in how it encourages many theists to deny the negative effects of mental illness and climate change. Because the existence of these things imply that, if there is an agency behind everything, that agency doesn't have our best interests in mind, they refuse to consider that they are real. This denial delays or thwarts the prospect of working on and potentially fixing issues that inhibit individuals' well-being and threaten our lives.
SFT #2: Disbelief in Magic
Theists often misunderstand why I disbelieve the bible. Let me be clear--it's because of the talking animals, duplicating seafood, parting seas, magic plagues, transforming matter, and resurrections. There are other valid reasons to be skeptical, but reasons 1 thru 100 are all the violations of common experience and observation that are not naturally possible. The same reasons that theists, hopefully, would doubt a tagline like "based on a true story" for Lord of the Rings.
SFT #3: Seeing Through Most Any Apologetic Argument
How I see religious apologetic arguments:
Formation 1.
Make an assumption that can only be true if God is real.
Use that assumption to say God is real.
Formation 2.
Find something with an incomplete explanation.
Substitute with a complete explanation based on the assumption that only God can be responsible.
Use that assumption to say God is real.
(In both cases, it would burn less calories to just assume God is real.)
