Beliefs are fine. However, problems arise when you are willing to judge others and make decisions with serious repercussions based on beliefs supported by little to no evidence; or worse, beliefs refuted by evidence.<quoted text>fail
Forming beliefs is thus one of the most basic and important features of the mind, and the concept of belief plays a crucial role in both philosophy of mind and epistemology.
Thoughts like: "We shouldn't worry about climate change, because whatever God wants to happen will." "I look forward to the dying, because then everything will be perfect." "Science is meaningless. God doesn't mean us to understand things better than we already do. " Or my favorite: "My religion should be backed by legislation, and should be the official religion of the state, even though it is no older, is backed by no more evidence, and has never been demonstrated as better for society than any other belief system."
Such thoughts all demonstrate a lack of logic, a narcissistic certainty in the superiority of your own beliefs, and a destructive "us against them" world view.
It's fine to have religion, but you should be open minded enough to accept that other people have a right to believe other things, or to try to understand the universe, even if what we discover does not support your beliefs and makes you uncomfortable in your faith.
So back to religion in schools: If you really think your faith based beliefs should be taught universally in public classrooms, you really need a more open minded, critical outlook. Your thought process is very nonconstructive.
