One of these days, I’m still hopeful, we will figure out that behaviors are taught, usually by parents. Intentionally or accidentally, kids learn from what they see.
I don’t care what nationality you are, or what your skin color happens to be, the root cause is how kids are reared.
In my head it’s so simple.
Not just kids - it's about one's whole life, including the adulthood, to the very last moments. We tend to change a lot over the courses of our lives, constantly being affected by our surroundings.
