The First Amendment guarantees the freedoms of speech and association. This is still a free country, in spite of the best efforts of intolerant leftist know-nothings, and any group of people can get together and talk all they like about how people of this or that race, nationality, religion, etc. are the scourge of the earth and have no right to live. Any American has the right to hate the living guts on anyone he damn well pleases, for any reason whatever, and to say so.
