If you make that decision that's entirely up to you and absolutely fine but do you have to keep telling people? People are being really nasty about it with a definite undertone of I'm a better parent/I love my children more than you do.
Lots of people will have to send their children back for all sorts of perfectly reasonable reasons. Some children really need to be back at school for their own safety and wellbeing.
Parents taking those decisions have enough on their plates, why would you want to add your judgement to that? And why would you want social stigma to prevent children who need to go back being sent back?
Stop looking for validation for your decision and trying to take it away from theirs. If you're happy, that's fine. Making other people miserable helps you how?
