AAAS - What is AAAS?
They do not restrict their membership in any way, so if you think you are proving anything by posting the PEW Research quoting from the press release of the AAAS you failed.
As for the thread you mentioned, I made it a policy after I read Tank's firs thread not to read any thread he starts. I treat racists with contempt and ignore them as much as possible. Why go into a thread where one racists is trying to prove how stupid another racist is?
