Calibasco,
either I misunderstood you or you're mixing up completely differerent things.

Firstly, Hispanics were not such, but various peoples and civilisations, when the Spanish came and imposed their religion on them. That was a few centuries ago, but nowadays the fact is Hispanics are discriminated in the States, although things are inevitably going to change for purely demographical reasons.

Secondly, whatever riches the US industrial machine, as you call it, may have brought to previously non "colonised" parts of North America, the fact is that the majority of its native inhabitants were either slaughtered while fighting the invading US army or gradually annihilated as a people through imprisonment in controlled camps, and that was all done by the US government.

As for the Afro-Americans, I wasn't trying to blame you for slavery, but everyone knows that black people have suffered brutal discrimination in large parts of the US way after slavery was oficially abolished. In fact, it is pretty obvious that things have only got better to an extent for black people in the States; they are still discriminated in thousands of subtle and less subtle ways, and they constitute a disproportionate high percentage of the immate population in the US and are several times more likely to be executed than white people for the same crime.
Does any of this sound like tolerance to you?
Thought so.
So please, please, no more lessons from the US on that issue.
Cheers.
