You are taking the chance of damaging your child's future. I really don't think it's worth the risk.
Should I say something to the guy, yes, I believe so. Not to belittle or attack the guy, but maybe a little education. If he's a long time shooter then I can only assume he doesn't really give a crap about his kid(s).
Mind my own business..........the kids health care expenses may be mine and your responsibility in the future, I refuse to accept paying for stupid!!!
