Chuck Norris is well-known to be a pure conservative absolutely not for the gay marriage.
"U.S. Public Schools: Progressive Indoctrination Camps" is the title of one of these comments. What a program!
He writes for example that "it is also no surprise that an average of 6,000 students every year is leaving the approximately 94,000 public schools in America. If the power-to-be over our public schools, like government and unions, continue to oppose conservative curricula and impose overarching liberal educational revisions and laws, public schools will continue to experience an exodus."
He also uses quotation adding to his comment the words of Jim Nelson, author on Freefall of the American University: "the clear biases pervading our public academic settings. Among that lopsidedness is the intentional training of students to disdain America, freely experiment sexually, forcefully defend issues like abortion and homosexuality, as well as become cultural advocates for political correctness, relativism, globalization, green agendas and tolerance for all."
In short he doesn't like homosexuality, tolerance, freedom,... well he does not like a lot of things.
