Ostensibly, we forced “religion” out of schools.
But really, what we have done is to allow a false religion to be created, made out of depraved sexual perversions, and destructive cultural Marxism, and for that religion to be taught in schools instead of any positive religion. We've almost literally forced God out of the schools, and let Satan in to take His place.
If we are not to allow God's religion to be taught in schools, then we need at least equally to not allow Satan's religion in either. I think it is an error to treat evil as equal to good, but here, we are openly allowing evil to be elevated above good.
