Freedom of Speech"If liberty means anything at all, it means the right to tell people what they do not want to hear." -George Orwell.
I don't agree with the message that the "I hate white people" group promotes, but nevertheless they have the right to express their opinion.
Is their group immature, racist, ignorant, and inappropriate? Yes. All of the above.
But just because you disagree with what they are saying does not mean you should be calling for the group to be deleted.
