The instinctual violence was more on the VUX side than the Human, as far as I could tell. I'm not sure the tragedy could have been avoided, though-- even if Rand hadn't sparked the Insult thing, your countrymen would have found something else to justify their hate.

English, mostly, though I picked up pieces of other languages from the people who had been born on Earth-- just enough to recognize them if they're written out, mostly, though I know German a bit better, enough to construct simple sentences.

Humans seemed to have managed writing with hands for a few thousand years. :) It's not all that difficult, once you get used to it.
Do you know which of your hands is dominant, or are you ambidextrous?
