I don't get the opposition against this. There's plenty of Jewish and, especially muslim schools in the US that teach only creationism. Hell, some of them do so to the exclusion of not just biology but all science. They do so, generally, with public funding.
I don't get the position. There can only be one stance as far as I'm concerned. Either teaching kids science including evolution is mandatory and the state goes after anything different (AND checks), or they do none of that.
Those Christian schools referenced here are not a problem : they teach kids science and prepare them well for life, scientifically and otherwise. Compare that to orthodox Jewish schools or sharia-oriented schools.
I hate that nobody ever discusses the real problems. Unlike canon law (which no christians even follow), sharia law is fundamentally sexist and discriminatory, is pro-slavery ("advises against it", but has the most flexible slavery laws known to history. Islam is the only known religion, EVER[1], that allows killing slaves for fun, something not even the Romans dared to do (yes, gladiators were personally compensated, they and their families, and had to agree (to a similar degree as one "agrees" to a job, right. Legally you have a choice. In practice, saying no may have unacceptable consequences, generally the mines or a galley). Only people in the arena that didn't at one point legally chose to be there were criminals convicted to death)). This is being taught, both to small kids and adults. Why isn't it outlawed to teach this, completely ?
My point is: there are far worse things taught in public education to kids than skipping a small part of biology, while keeping science education generally intact (as much as one can reasonably expect from a public school at least). Why is this thing a focus of anyone ? Why is it allowed to teach people to kill other in response to what any American would consider freedom of speech ? To teach people to follow slavery laws and so on. I mean, given that that is not just being done, but growing. I feel that creationism is the least of anyone's religious education problems.
