Apparently you know very little of the Muslim/Islamic belief system - or it is just convenient for you to omit? I have never advocated a government forced religion so you apparently go there just to obsfucate my post.
Regarding arithmetic - the government stopped teaching with the old tried and true methods - now they teach 'new math' in addition to teaching 'whole-word reading' rather than phonics.
Maybe you are also unaware that the more government has tried to 'help' the school educate the masses better the lower the SAT scores have dropped while at the same time taking higher and higher percentages of taxpayers money to 'fix' the problem(s)...
I have no idea what phantom you are responding to. I have not defended government schools.
But government schools teach many things that contradict a literal reading of the Bible. The earth moves. Pi does not equal three. Bats are not birds. Grasshoppers have more than four legs. The sun does not orbit the earth.
