I have tried to model politeness to my children.
I refuse to play along with the offensive-word-du-jour thing. We are teaching our children that they have rights but not that they have responsibilities. We're teaching them that they may demand to be free from any implicit or explicit insult, but we're not teaching them how to respond, reply, or react to others with kindness and politeness and civility.
I don't like the terms that have cropped up that are used to describe an entire group of a type of person. I believe you can be heterosexual but not feel hatred towards homosexuals, and vice versa. I hate the fact that the words homophobia and transphobia have overtaken our conversations, as though certain people are afraid of people who follow a different lifestyle. Call it what it is: some people are filled with hate and anger and some people live their lives in peace with those around them, regardless of differences.
And I don't like, and refuse to kowtow to (ha! irony there!) referring to anyone as being "of color". What am I? Colorless? I am of Swedish and Dutch descent, so pretty fair-skinned, green eyes, blond-ish hair, etc. But I'm not transparent. I have a color. Everyone has a color.
I think that we are teaching our children the exact opposite of what we should be teaching them. We actually are teaching them to separate groups of people according to race. Examples: major awards ceremonies that are only for black people who have achieved a certain notoriety (often sponsored or led by someone who is squawking about being equal and ridding the world of black vs white animosity). And schools that observe _____ History Month (Black, Asian, Pacific Island, etc), where people are only on the list because of their skin color or ethnicity. Why don't we celebrate human being's contribution to humanity? For example: Performing Arts Month, where people like Kiri Te Kawana, Ray Charles, Yo Yo Ma, Beverly Sills, Taylor Swift, Paul McCartney, Itzhak Perlman, Marian Anderson, Paul Robeson, Bernadette Peters, Lena Horne, to name just a few, are celebrated for their efforts, their relentless pursuit of their craft, the way they overcame certain obstacles. And see? That list encompasses many races and ethnicities, genders, disabilities, performing styles, etc. Do that for medical contributions, government and politics, visual arts like painting and sculpture, technology, architecture, first responders and law enforcement officers, military, etc. Teach children to look past colors and towards being a productive citizen of this planet.
I understand that if we examined the colloquialisms and expressions that we use, from a psycholinguistic and etymological perspective, we'd be surprised, shocked, saddened, amused. How many of us have used the term "grandfather clause" when describing a rent increase or business arrangement? How many of us have complained about being in the "peanut gallery" at a sporting event or concert? We can't realistically cleanse our language of all phrases that may be based in a practice that we abhor.
What we can do is help our children realize that words can hurt, that words can heal, and to think carefully before they speak about which choice they're making - the hurtful or the healing? And we can help them realize that sometimes words are spoken with intentional cruelty, and how to respond without stooping down to the bully's level, and that sometimes words are spoken that are innocent in intention, and how not to find offense in everything that happens during the day.
