Some people say things in such absolutes, as if all topics could be easily defined and understood, as if every issue could be solved with a simple and specific answer.

As most of us have observed, not everything is black and white: there are millions of shades of grey. And once we realize that, we see how the varying shades can open a number of nuances into the originally-thought-simple topic. What can really get our minds going is when, after that, we begin to learn that there are colours in addition to those greys! And colours are where we'll start to fluorish. A person knowing only black and white (which aren't considered colours, by the way) can only function well in a black-and-white world. In a world filled with greyscales, one might consider that person as lacking skills needed to deal with grey areas.

Someone with a different colour tint on a subject simply sees it differently. There's no problem with that: it doesn't mean they are "screwed up" so much as possessing different viewpoints. And once we appreciate those differences fully, we can see them as opportunities instead of threats. These are chances to learn about other colours and see what makes them so brilliant, so vivid, experience the contrasts and harmonies they make with other colours! Then we can enjoy and celebrate these deviations, instead of scoffing or just dismissing them without true consideration.

Colours allow expression and variants. Variety is the spice of life! If you don't want them around, you're living in the wrong place. (Try the next planet over.)
