Yes, Christians are being opressed by the public school system that keeps teaching moral relativism and undermining the moral foundations of the world's youth.
And guess who makes up the rules in public schools? Christians themselves! There are many Christians I know that don't want their own religion, albeit born into, forced down their throats. I know I have been written off as a disgruntled CINO that's just acting out in the past, but there is a lot of truth to it.
I of coruse support the right of children to secede form their parents and declare independence.
There is no merit in forcing Christianity on someone, because only where sinners are present in their condition can the glory of God shine properly through the elect.
