Even deeper is a discussion of what counts as being biased against a gender/race. Is supporting child support policies biased against men because men are more often to end up in jail for not paying? Is supporting abortion bans bias against women because women are more often to end up in jail for seeking an abortion anyways? Is supporting university affirmative action being anti-minority because they hurt Asians? Is opposing university affirmative action being anti-minority because they help African Americans?
Asking for citations has, from what I've seen in the past, ended with people giving citations of what they think constitute a bias that the other side doesn't consider a bias.
