Some time ago I was out on a pleasant day riding my bike to the park. Up ahead on the sidewalk was a little girl, perhaps 3 or 4 years old, in a pretty dress smiling at me as I approached. I said "hi" and she let out the most chilling set of obscenities and curses I've ever heard, all the while smiling and waving her little hand at me, obviously having no understanding of anything she was saying as I rode past. I suspect there is only one place she could have picked up these words and phrases. The power of parenting, for better or worse, amply demonstrated. Children absorb the world around them, even if parents and guardians and other adults around them wish it were otherwise. I can't believe there is ever any harm in presenting and modeling care, compassion and acceptance of others, whoever and whatever they may be. I do think you keyed in a important factor in that many adults may be afraid of the awkward questions their children may ask about topics that scare them as adults.
