What constitutes hate with freedom of speech?

In Canada, advocating genocide or inciting hatred against any 'identifiable group' is an indictable offense under the Criminal Code of Canada with maximum terms of two to fourteen years. An 'identifiable group' is defined as 'any section of the public distinguished by colour, race, religion, ethnic origin or ual orientation.' It makes exceptions for cases of statements of truth, and subjects of public debate and religious doctrine. The landmark judicial decision on the constitutionality of this law was R. v. Keegstra (1990).
