Blame Capablanca-Fan, who spammed the thread with a lengthy political argument with only one mention of Leak! And pointing out Leak was a hypocrite is fair comment - unless he did a cartoon opposing the NT intervention, of course - it doesn't have to be a tribute thread.
Your final sentences make no sense, as of course there can be cartoons about black people. If Leak can criticise Aborigines, then why can't I criticise him - I'm not trying to censor his cartoons?
