I notice that definition doesn't include inciting hatred towards people because of their gender or sexual orientation. I think that kind of shows the limitations of these laws, you can't ban hate speech against any group because there are many groups that seem to "deserve" it. So instead you have to explicitly list out the groups which don't deserve it. This picking and choosing of specially protected groups can get pretty ugly, like in the USA the hate crime laws have been expended to include law enforcement as a protected group.
