Your avoiding the issue; name the law against the speech against speaking out about Darwinism or Evolution in the US?
I'm not avoiding any issue. There shouldn't be any restrictions on speech regarding this debate, but I don't expect a secular government to support creationist theory in publicly supported schools. That is why I made sure my children were educated in Parochial school.
My guess is that you would be equally irritated if the government presented Judeo-Christian as one of many creationist theories that also included Hindu, Buddhist, Mayan, Incan, Taoist, Zoroastrian, Baal, Druid and animist.
