/r/insaneparents is a weird place where you can post those crazy parents who post in those woo-woo anti-vax groups on facebook and do things harmful (directly and indirectly) to their children. Things posted here do not have to be physically abusive. Abusive and insane are not mutually exclusive. The Anti-Vax mom you know isn't legally abusive, but you know she's insane for not vaxxing her kid.
