This is an incredibly complex issue. As a left-leaning person who wants to see discrimination eradicated, but as a person who also wants to see it eradicated without it being the purview of some constellation of legal obligations, I recognize deep rooted conflicts.
Take for example the ACLU's (IMO correct) defense of Neo Nazi groups to march in solidarity. This is the type of freedom that our country is based on. It's not something I personally affirm, but I have to defend the right on principle.
Tom Cook talks up one side of the issue. His credentials have nothing to do with the topic. If we were in a critical thinking class we would recognize this as a cut and clear case of an appeal from authority.
Can we get something more substantive?
