what do you call a  year old boy with no friends or parents ? a sandy hook survivor whose parents were avid country music enthusiasts .
Is this a joke about mass shootings?  What do you mean to imply about the victims?
It's all a joke, how can anyone be serious about such jokes.
I don't even understand the punchline of your joke, since it doesn't make much sense to me.  However, the point remains that mass shootings, especially of children, are no laughing matter.  Someone hearing your joke might have lost a loved one in that massacre, and you wouldn't want to subject them to such a painful reminder.
