This is not an issue of free speech, since there will always be places on the Internet to discuss these topics, the question is whether CMF wants to be one of those places, or whether it wants to focus on retirement and financial planning. As I noted, it is not my choice, it is the choice of the people who own the forum. Some people think that their right to free speech means they should be able to say whatever they want to on CMF. I recognize it as a business, and the owners of the business get to decide what is discussed.
I have been told to shut up in the Hot Button discussion, but have never told anyone else to do so because I know it doesn't work. Pointing out when someone is being racist does not limit their free speech. Telling someone not to point out when someone else is being racist is a limitation on free speech.
