Dr. Ken Miller and Dr. Francis Collins put the lie to your contention that evolution=atheism. There are a great number of evolutionary biologists that are also theists.You mean atheism as religion (disguised as 'evolution') gets a free pass, and a bully pulpit in which to pollute and proselytize young minds, just forming opinions about reality, into anti-Theistic bigotry within Americana academia. But allow a class to show the overt weaknesses of the Darwinian scientism fairy-tale and now we have law suites.
So much for freedom of speech and freedom of thought. Darwin is GOD!! Thou shall not take the name of thy lord god in vain!!
Sieg Heil Darwinism!! Long Live Dawkins!! Supreme Ayatollah of anti-Theistic scientific thought!! No religious Blasphemers allowed!!
As for bigotry, perhaps you should examine your own feelings toward atheists. You seem to paint them all with the same brush, which is pretty much the definition of a bigot.
