Of course, it's not just the religion of evolution that the schools teach in opposition to Christianity.
I had to tell my daughter when she was in kindergarden about Islamic suicide bombers, because the dang school taught her that Ramadan was good because Muslims gave to the poor.
I shouldn't have had to have that conversation with them either. But as long as the anti-Christians are pushing their agendas in the elementary schools, our choices are to either counter it with the truth or yank the kids out of the public schools.
Did you also teach your daughter that Islam officially endorses Creationism? Most Islamic countries forbid the teaching of evolutionary theory.
