In regards to other talks why bring up Protestantism or Rousseau education. If you bring it up people will look into it.
https://en.wikipedia.org/wiki/Jean-Jacques_Rousseau ( I have never heard of him. ).
Who cares about Rousseau, Protestants or theology of the body? Bring up how Catholics should raise children. Supply people with traditional Catholic resources.
I think most traditional Catholic parents are intelligent enough to talk to their children about God and marriage. Many things should be private and not public.
The main thing is to keep children, teens off all social media period. If they need one then get one without text and internet. They are bombarding everyone with shady evil info and advertisements.
Temptation. It is getting worse.
