Nicely written. And going on the offensive with a national "toy guns go to school day" could be quite effective. Maybe the campaign runs with a slogan such as "Children Distinguishing Differences: toy gun, real gun, toy gun, real gun."
Rather than gun owners remaining silent, hoping to be left alone, this could become the opportunity to speak to children. This could be a time to speak the truth--that guns are a means by which any of us can even the odds against bad guys.
So, Steve, what date did you have in mind for this national day?
