Did you know that the average student who attends public school will spend over 100,000 hours in school? That is over 100,000 hours of being influenced with strangers beliefs and values.
I have no problem with someone having different beliefs and values than me, but I want to make sure my children are influenced by what my husband and I believe and value.
This is one of the reasons why you are more than qualified to teach your own children. You get to be an influence for good to them in a chaotic world. You are doing a marvelous work, so keep going.
