If what you believe, is true, and what you believe is not true (what others believe), is not true: would that make you open for different perspectives?
How about what you believe is your current worldview.
And what you believe not to be true, is a different perspective.
That would totally make you open for different perspectives. Because it might change your worldview.
It’s a matter of how open you are for different truths. And that could just bring everyone more together.
