Apparently Steve is trying to make the point that modern PC culture selects a specific group or individual to demonize, implying that what they did was extraordinarily evil when compared to the innocence of other groups of peoples. Peoples around the world did and do things that should be condemned given today's morality. It does not mean that evil of one culture should be excused because some other culture does evil. It is quite proper to condemn the actions of the Spanish conquistadors just as it is quite proper to condemn the actions of the Maya for raiding other cities for captives then sacrificing them by cutting their hears out while they are still alive as sacrifices to their gods.
In our current PC culture, it is a "good" to condemn Europeans today because, in the past, some Europeans engaged in despicable actions. But any condemnation today of past despicable actions by cultures that are not European is called "racism".
Who said that cultures of any sort were beyond criticism? No one in this thread. This thread is about whether Columbus actions were excusable. Bringing up the war career of Chief Seattle is as relevant as complaining about Napoleon in a thread about the conquest of India by the Mughals.
I don't see anyone here excessively praising the Taino nations, or indeed having any idea who they are or were. They certainly weren't pacifists, but that shouldn't have any bearing on whether Columbus' actions were right or wrong. By his own accounts, he was killing people for money, political conquest, and sexual access. Not to liberate the Caribs from Taino attacks. And definitely not to save people from the depredations of the 19th Sioux, however that might work. Those peoples are connected only by Steve's belief that they are of the same "race".
