Respect is earned, not handed out on demand

Sing it, sister

Don't want people insulting your child or your parenting skills? Then use those skills to raise a reasonably well-behaved child. If you're tired of hearing childfree people complain about parents and children, then don't give us any ammunition. We're just as tired of complaining about your (and your children's) selfish and inconsiderate behavior. Remedy that behavior and watch the complaints and snarky comments dwindle to nothing. You can do it, if you really want to. Then again, maybe you'd rather just complain right back at us.
