Why is it a fact? I'm independent, so I usually let the other two sides battle it out among themselves, while I stand by and am usually quite impressed by the sophisticated and clever arguments going both ways. I have yet to be swayed either way. Still, it's interesting!
In a way it's an optimization. My hope is that one day, when the two sides have finally come to a conclusion as to which one is right, I can join that one, and save myself a lot of trouble in the meantime ;)
