How do Americans feel about the way Native Americans were treated?

[Howlin Mad Missy]

And on another note how did you Brits treat the Irish

Slightly different story there... struggling to see the relevance to this topic (or the harsh criticism you're reacting to for that matter)

To be fair, some connections (particularly in early American history) can be drawn between the two people and the way in which the British viewed them (I've heard credible arguments that assert the Irish were worse of than the Natives during the 16th/17th century), but by and the situations are pretty dissimilar.

Indeed we a had something of a war but I don't recall it being policy to infect them with smallpox. Hitler would have been proud. And yes I do believe it a genocide.
