The answer is, "They learn it from us."
Competition by its very nature produces bullies and bullying behavior. As long as we label some people as winners -- not in the sense of the person being ethical, empathic and kind, but by measures such as wealth and other privileges -- we create thereby a power circle with outsiders who are left vulnerable to bullying and intimidation in as many various forms as there are stars in the sky, within the bounds (barely) of what is defined as being legal. When it comes to finding ways of building oneself up by putting someone else down, we are limited only by our imaginations.
Who has not been silent witness to workplace violence -- the verbal kind, where someone who has power and standing in an organization uses it to whale on someone who has less? Who among us is brave enough to speak for the bullied person? Human nature dictates that we must pretend not to see, or else must rationalize it as being the victim's fault.
Some of the worst abuses I've witnessed or been subjected to were from women who call themselves feminists. Now whenever I hear the word feminist I dive for cover under my desk.
We all get victimized sometimes, as my friend Coach Barry likes to say, but we keep trying, and saying, "I'm NOT going down again!" (he does great pep talks!). It's true.
But with all due respect to Coach Barry, I'd like children to grow up in a world where nobody ever has to say, "We all get victimized sometimes." That's my idea of heaven.
