Since most American schools and our prisons are cess pools for political correctness...the hard slog as you put it can be made a bit easier by bringing prayer, factual history, straight math and science back to our schools with out the clutter of useless Black history month, Common Core, a travesty; catering to Islam needs in our schools is utterly stupid and I suspect, unconstitutional...see what your state allows prisons to teach, and who is doing the teaching.
I agree with all you said, but that will require the long slog I mentioned.
