Everyone has something they can't stop themselves from nerding out over - but often it's hard to find people to talk to about it. So go ahead, share your interests, and tell us about them!
Smacking children and how it literally has no benefit to the child whatsoever, and makes you a bad parent if you still do it.
I used to be a strong supporter of smacking kids, I even signed a government petition to revoke the NZ anti-smacking bill, but after studying it at uni and then keeping abreast of the research afterwards, it has only negative effects, and yet bad parents still defend it.
Hard to talk about because people get weirdly defensive even when there's NO evidence that smacking kids is either beneficial or effective.
