Belief is a powerful thing - it can get us through trials and horrors that would otherwise defeat us. But when belief becomes blind acceptance, or zealotry, or a reason to refuse to learn, it becomes a danger to the community.
There is a different between religion and science - religion is based on mythology and belief, science is based on provable fact. One is a personal set of guidelines, the other is empirical truth anywhere in the world. In short, facts trump belief every time.
If your belief is keeping you from accepting truths (homosexuality is not a choice, global warming is real, trickle-down economics doesn't work, etc.), your beliefs are harming your community, be it personal, local, or global. Put your faith in that which is actually knowlable versus that which is simply believable.
