Comment: You are right. I am an immigrant and so grateful to be here and will celebrate 150 with great pride. 
Having said all that, I am indigenous from the former British colony, Ireland. Our religion was banned, our language destroyed, all our land taken (without treaties), and our population halved by famine. So, I understand the indigenous argument - it is a bit tricky to be gung-ho about the first government that set up residential schools. I think Renzetti was pointing out that discomfort, not saying we shouldn't celebrate.
