The simplest and most powerful reply to this is that politicians cannot and should not be allowed to legislate what is valid science.

We need only remember that Einstein's ideas were attacked in Germany because it was "Jewish" physics.
In the Soviet Union, Linus Pauling 's idea of resonance (in chemistry) was proscribed by the government for political reasons. Of course Einstein and Pauling were correct, but the damage to science in both countries had been done.

Anybody who attacks this on any other level than by not understanding that science is self regulating and that the politicians' legislation is not in any way about science or education, but about promoting a human ideology, has missed the boat completely.
Tim Moore and his ilk are liars, and they do not care about science, only their personal agendas.
