Your mother is very bright, just like her daughters. In the wake of these attacks, and of old prejudices coming to light on the internet, she pointed out how our generation has had to tiptoe around the ideas of gender, race, sexual orientation and other societal taboos.
But these aren't taboo for you and your friends. They just are. You accept that a boy and a girl can get married and believe whatever they want, as long as their beliefs don't hurt somebody else. You know that a boy and a boy can get married, or a girl and a girl can get married, and that's cool too "as long as people getting married love each other" (your words, Scottie). It's not strange at all to meet someone whose skin is a different color than yours. Why would you treat them any differently, you ask, as if even the idea that someone could do that is absurd. If a Muslim woman wears a hijab, you ask what it is, and why she's wearing it. Sometimes you'll ask her directly. If not, we turn to books and the internet to discover something else about our global community, something special.
Pepper, you're three and you're speaking a little Spanish. You long to learn French, Scottie, and you know quite a bit of Spanish and Italian. You've expressed an interest and have received a little instruction in American Sign Language. You want to communicate, and talking to your friends when I play with you on the playground before school, I've found that they love interacting with their community. Sometimes that interaction includes hurling a red ball at my head, but you do that too from time to time. It's okay.
For all my fears (which will always exist), you're both exceptional human beings. You both know there are "bad guys and gals" in the world, but you know, truly know and believe, that the world is comprised mostly of "good guys and gals".
You continue to fight for what you believe, on a macro and a micro scale. Please keep fighting, and keep telling Mom and me about your conflicts and your confusion. You will triumph, for you are both a triumph simply by trying to do good. And guess what? Mom and I are with you. We have your backs, and you have ours.
