I think what is being pointed out by African-Americans is that from slavery forward they have been living in a supposed democracy which treats them as less than other citizens, less than whites in the society. And I think that pointing out that there are structures of discrimination in the society, deeply rooted racist structures, that segregate housing, that send black children to ill-equipped schools, that discriminate in the workplace - these are truths about our society that must be faced.

The common good is the notion of shared collective responsibility and reciprocity. It's that that we've lost.

The growing gap between rich and poor, the seeming lack of concern for the health and well-being of ordinary people, the obscene salaries made by CEOs who are increasing profits by moving their plants to places where labor is cheap - that's where the problem is, not in schools, colleges and universities.

Free speech is what we all have and is guaranteed by the First Amendment of the US Constitution. Academic freedom refers to what happens in the university, particularly in the classroom, and to the importance of the teacher having the right to teach and share what he or she has learned, has proven her competence to teach, having gone through a series of tests and certifications including research and writing to demonstrate her abilities and knowledge.

If the students don't want to learn about evolution, they shouldn't be in the course. A biology course that teaches creationism is not a science course, it's a religion course. So the students demanding that creationism be given credence in that course are out of line and are denying the academic freedom of the professor. They are calling into question the scientific basis of the material that's being presented. And students are not in a position to do that.
