Relativity

What do you believe? If you had been born in China or the Middle-East, into a multi-millionaire family or a penniless one, as a lovechild or an family of seven, would you still be believing the same things? The answer is no, of course not. You wouldn't even the same person.

People cannot control who they are born to or where they are. We don't choose our circumstances. Our circumstances are handed to us, whether we like them (our circumstances) or not.

Now, back to what you presently believe. Are you religious? If your religion is the correct one, then are other religions false?

Let's say for the sake of this example that you are Buddhist. In a hypothetical reality, you were born into a Catholic family and raised with Christian beliefs. And in another hypothetical reality you were born into a Muslim family with Islamic beliefs.

You would in each reality believe that your then-current beliefs were true, and that the other beliefs were false. Hopefully you see where I'm going with this.

This isn't to say that belief is bad. Rather, this has more to do with dis-belief. It is fine to believe, but it is not fine to immediately discount all opposing points of view, especially when talking about religion. The definition of faith is belief without evidence. And as such, how is it fair to claim that someone else is wrong when in their shoes you would claim the opposite?

Religion is the big kahuna of belief, but not the sole example. Consider global warming, political opinions, vegetarianism, or what have you. People will tend to be resistant to other points of view, which is natural. But that isn't an excuse for ignorance. We must always be open to the possibility of being wrong, incorrect, or a little off. Being off is okay. But being ignorant and unfairly rejecting opposing beliefs is not.

Mind that there is no "us" or "them"; there are only "people" and "more people".
