Once the young leave the campuses, and schools. They get a un-adultered totally oppositve view of the world than what they were taught. They aren’t prepared very well, but most learn that everything they were taught was a lie. That’s why young liberals turn into conservatives as time goes on.
I grew up going to church and therefore learning about Israel. The vast majority of Christians support Israel. Not many kids grow up in church these days.
