Dawkins Talking Atheism in a Public School?

The complaint would be “Dr. Dawkins mentioned God in the science classroom of a public school. According to Dr. Patrick Trischitta, who is associated with the Freedom from Religion Foundation and has experience with many similar such cases, it is against the Constitution to mention God in the classroom. Therefore, Dr. Dawkins is in violation of the US Constitution.”

This is a valid complaint right? I’m just quoting what you said.
