The proper 'context' for ethnic hatred

The Canadian Supreme Court unanimously ordered a Rwandan man accused of inciting massacres to be deported back to his homeland.

The court said there is well-founded evidence that Leon Mugesera encouraged the violence in which Hutus killed an estimated 800,000 Tutsis in 1994, reports the BBC. The case rests on a speech he made 18 months before in which he allegedly called for the extermination of Tutsis. Mr Mugesera has always claimed that his speech was taken out of context.

Specifically:

In a speech made in 1992, which was caught on videotape, he is seen apparently telling more than 1,000 party members that they should kill Tutsis and dump their bodies in the river. He referred to Tutsis as cockroaches, and said they should be exterminated.

Now if this isn't incitement to ethnic violence, then I wonder what the proper 'context' for such filth is.
