One of the most interesting mainstream debating forums is IQ² or Intelligence squared
.

It is an annual series of 'provocative and informative' live debates on the 'hot-button concerns' of the day such as Euthanasia, Nuclear Power, Internet Censorship or Freedom of expression. You can watch them all on their website. BUT THINK AGAIN.
The problem with these forums is that they are dominated by white males with token representation of white women and almost nonexistent non Anglo debaters. If Australia is multicultural society where are those Asian, Lebanese or Indians who have something to say.
Are those Indian engineers busy buidling these Nuclear Power plants or those Asian computer scientists administering Internet censorship if those white males decide that that needs to be done ????

Here is a research paper from Korea from
AsianPerspective.Org to put some of these white views in slightly different perspective and a book by a women

who sounds qualified enough to talk about it.
