What do you get when you mix red and yellow? Orange, of course.
So why do so many of us see the world in black and white. Every one of us knows exactly what is right and what is wrong. Funny how our certain knowledge differs from person to person. Could we both be right? In most cases, yes. Because we are all seeing orange, just different shades of it.
In a few cases, someone mixes red and yellow and sees blue. Oops. We have a problem. But most of us know the difference between right and wrong, appropriate and inappropriate, etc.
What to do? Hold on to your beliefs and values, as they are important to who you are. But respect others whose views might not be identical. After all, they are not you, and their beliefs and values are important to who they are, too.
