It wasn't always this way. There was a time when American teachers were more interested in education than peddling marxism and molesting their students.
(Last post about religion I promise, but this is my position.)
Religions are not interchangeable and while
some are completely antithetical to western life (curry and durka durka), that doesn't mean they're all equally bad and thus becoming Brian Griffin is the answer. Belief itself is not the enemy,
certain beliefs are.
If you ctrl+alt+delete religion people don't just suddenly transform into Voltaire, they simply replace God with the state. That's what always happens.
People
need unifying, guiding ideals and identities, and even more critically they need something to make those things more important than just a single person or movement or philosophy, it has to mean more than just how you feel at a particular point in time and has to be greater than just the individual.
I'd rather a great unifying belief system come from a man in the sky who says murder is wrong than have it come from a bobby caving my skull in with a dildo because I made a tweet calling Keir a fanny. Christ doesn't tell you to annihilate all infidels and lie as much as possible so you can infiltrate their societies and destroy them from within at the tip of a knife, and at this point I think that's a pretty good standard for a belief system in a civilized society.
