I wish it also meant a right to speak your mind free from the judgment of your employer, or university, but that is a slippery slope. Just because I will defend a person's right to speak their mind no matter what, does not mean I have to listen to it, or agree with it.
I wrestle with this, because if I had an opinion, pick any social issue, I don't think an employer should be allowed to fire me because of that.
However, we have freedom of association, and a business may not want to associate with someone who has opinions counter to their own.
