Dante Let us consider the untouchables in India. Could you tell me what percentage affirmative action (called reservations in India) are for untouchables and other disadvantaged groups? Answer: minimum 50 percent in every province, and 69 percent in Tamil Nadu. In other words, out of every engineering seats in colleges, 50 to 69 seats are reserved for untouchables. 

In Canada, less than 5 percent of engineering seats are reserved for natives. In the US, there is no explicit affirmative action based on race. Race can only be one factor in admissions.

Second, India's Constitution was written by an untouchable. All untouchables for the right to vote in 1947. Canada's natives got the right to vote in 1960. American blacks in the south got it in 1965.

Finally, an untouchable woman has been the provincial premier in India's largest state for two decades. No minority woman has done so in Canada or the US. Even Obama was half white.
