What we're really seeing in all this is so many parents are insecure in their parenting and decisions that they feel the need to jump to "do it my way or you're the literal devil."

If we take the charitable view, it's that things like "cloth diapers saved so much money I'm sad others don't try it" - which may be entirely true. But trying to use things like "if you use a diaper you are the cause of climate change" is something beyond.
