Constitutional rights are about what the government can and cannot do. They do not apply to private entities. I guarantee that if you come into my living room and call me names or otherwise offend me, you will find your ass quickly kicked out of my house. If I don’t like you, you won’t be coming into my house to begin with to express your opinions. I have the right to do that. This ruling does not force Facebook to allow in sex offenders but it is a huge step in finally putting a leash on the government dogs, a very long leash but a leash nonetheless.
