If that's accurate then it seems a lot like the Texas ciriculum in question. Neither have been implemented and both have their supporters who would like to see them implemented.Is there actually a school system anywhere in America where "My Two Dads" is part of the official curriculum?
While I am one billion percent certain the basic theory of Evolution is accurate I can understand those who oppose it for religious reasons.
Some Christians see teaching evolution as the Public School telling their children that their religion is a scam.
And you may say "Well their religion IS a friggin scam" and I'd understand that sentiment too.
But when the people who believe in Creationism are the majority, they are going to do their best to preserve(and further) their beliefs.
I say teach them both as theories and let the chips fall where they may, but like with a lot of things today a line has been drawn in the sand and you're "either with us or against us".
And if it concerns you enough, take the responsibilty of teaching this one very small lesson to your kids and don't rely on the public schools to teach this topic.
In my opinion a good percentage of teachers follow a ciriculum, but also teach from personal experience and beliefs. As a parent I may not always agree with these beliefs but if I allow said teacher to shape my child more than I do, I suck as a parent.
