Please help me respond to this angry letter.

I really question whether or not one should even address such idiocy and racism, however since you obviously have your heart in the right place as already mentioned and you seem extremely patient with such feeble-minded intolerance then here is a nice and concise summary of what is going on in Caledonia that frames it within a much larger and necessary context (one that the media fails miserably at discussing). This was written by an expert on First Nations issues:

 "I can tell you quickly that this land dispute goes back to the end of the American Revolution, followed by the settlement of Upper Canada in the 19th century. when white squatters were permitted to take 6 Nations land on the pretext that they (squatters) were supposedly developing. This was reinforced by the colonial elite that controlled the judiciary  (see Whiteman's Law).  When First Nations attempted to evict squatters, it was the Indian  found to be in the wrong. The 6 Nations continually protested against the illegal occupation and sale of their lands until laws in the 1920s banned the pursuit of land claims (6 months in jail). This was removed in 1951 creating the 'modern' land claim movement. Suits over rights and lands increased with the Supreme Court's decision in Calder c.1973, when Aboriginal rights were recognized by a colonial institution. After that the Trudeau government was forced to institute a land claims process. This lead to the mistaken belief by white Canadians that land claims were something new. It has also led to the assumption that land claims mean people will lose their land -- NEITHER IS TRUE. 

The 6 Nations have continued to fight their case before the courts and have continued to negotiate over different aspects of the violation of their lands. The governments of Canada -- provincial and federal -- have used misinformation, delaying tactics, and denial to block native claims based on a premise that they are a) not really important to Canadians, b) the general public when it comes down to it will not support the claims, c) Indians under the Indian Act will disappear hence no need to settle, d) too costly, e) you can add the rest.  The Caledonia plot of land I do believe was only occupied once it became apparent that the governments were not interested in settling after more than a decade of negotiations. The sale and construction of homes on the disputed land would be a slap in the face of anyone in that circumstance. For once the homes are built the land will never revert to the community and compensation is even harder to get. Hence the blockade. Police actions led to the increased tensions. Instead of negotiating the government continues to use its courts to force its will on poor and powerless people. 

The white people in the area instead of being racist assholes need to support the 6 Nations community -- this would speed the process and generate more community friendliness than anything else. I bet the government is hoping that the hostility among the whites will allow them to continue to ignore stuff ... Moreover, every one of those whites is an accomplice to the colonialism of this country -- by their taxes and the votes.  I would also like to add that the laws concerning land rights and aboriginal rights are based entirely on colonial law -- so I would say to the white settlers & their government follow your laws & those wishing to see them applied, then applying them equally, justly and fairly would not force the need to block a road.  After all it was the colonial courts and British/Canadian lawmakers that created these categories unilaterally. So follow your own laws ..."

P.S. So to summarize "the white people in the area instead of being racist assholes need to support the 6 Nations community."
