I am concerned about what people believe if those people believe things that negatively influence the way they treat others. If these beliefs are either demonstrably false or simply unproven, then I think we have a duty to point this out. There are a lot of people on these forums that, for example, think gay marriage is wrong. That is not something they can back up with empirical proof. I have every right to make my feelings about it known in an attempt to get them to act more reasonably. I'm sorry you don't seem to understand this.
