Golden Rule: Pick your superstition and STFU.
If your basis for believing in magical pixies is FAITH, then you have no business in trying to force it down other people’s throat and whilst claiming it as universal or divine truth. You have no business in condemning other people to swim in a lake of fire, and no business in trying to stick your superstition into politics. If your basis for believing in unicorns is FAITH, you have no business in trying to have it taught in the science classroom, and no excuse for acting like a complete nutcase going around waging jihads against nonbelievers. If you wish to offend people with your baseless superstition, then learn to be offended by criticism. The golden rule is this: Pick your superstition and STFU.
