While we're at it, lots of people say that the U.S. committed a huge crime by "stealing" this country from the then current owners. Any profit from that action? I'll bet there are some staggering numbers associated with the death toll among the natives as a result of our action there.
The bottom line is that a lot of things have happened throughout history. If it makes you feel better to blame someone, great. It's probably not going to do much to set thing right though.
They can say that all they want, but the facts do not tally with their claims.
Off topic post about your comment: for the Americas, some estimates range from about 50% (one of the most common) to a whopping 95% of the Amerindian population dying as an effect of European contact. Much of this was due to diseases the Europeans unwittingly brought, but some was due to warfare and harsh slavery conditions at the hands of the Europeans.
