Besides the gross injustices of modern schooling, there are the often forgotten opportunity costs... You have to have a heart of stone to not be affected by this one.
Exactly ! There are the opportunities that a lost to children when they attend godless government schools. The opportunities to teach the true love of Christ that arise throughout every day. All of this is missed in a godless government school. If some Christian teachers do try to sneak it in, unfortunately, they are teaching the children that Christians are sneaky.
At their very best, government schools could only offer up a very generic and lukewarm Protestantism. Those defending their government school educations that they remember from the 50s and 60s are like being color blind and not knowing it. How can a person explain what color ( or a truly religious education ) to someone who can't understand it? Like fish, they have swum in secularism they don't see or feel the secular water surrounding them.
I honestly don't think most are being malicious. They genuinely don't see.
