Curiosity facilitates learning and understanding. Understanding eliminates unfair judgement... which eliminates the many hurt feelings that are guaranteed to follow. It's not about changing what is true for us, it's about understanding where we are different and gaining a respect for why that is. There is beauty in opposites and there is power when they work together for good. When we see the "why", we don't have to wonder... and the only way to see the "why" is by being curious and not judgemental just like this tee exclaims.
