DY,
I’m going to assume that with your sarcasm you understood my point. And hey, even you admitted you do allow some secular media in your home (pre-screened books).
As kids get older, they dictate more and more where their chinuch is. Now of course, there are absolute limits, but every parent knows that some kids need different boundaries. You may allow some children to read more secular books than others. You may allow your child at some point to eat a hechsher which while technically kosher is not something you buy for your home.
This issue is neither black nor white. But letting my son watch Mickey Mouse vs reading the book is virtually the same (and I mean that literally – they right the Mickey Mouse Clubhouse books in the same format) is not harming his spiritual health. [Which is not to say you are doing anything wrong by not allowing your kids to]
