1. That's an opinion piece, not a piece of investigative journalism.
2. That's from 5 years ago; who knows if this is even still the case, even assuming it's as widespread as the opinion piece claims.
3. See my second point.
For what it's worth, both the pieces are part of a smear campaign by an American far right Christian group called Exodus Cry.
Among other things, Benjamin Nolot who runs Exodus Cry is a holocaust denier
I didn't know that, but it doesn't surprise me. The hyperconservative scumbags (alas I repeat myself) will stoop to anything to shove their beliefs on everyone else.
