I'll give you a concrete example of how our "FN brothers and sisters" are treated as lesser people. Someone I know (a white male) has been doing an applied research Phd at the University of Alberta in Edmonton, and has done courses that have  included a number of indigenous female students.  He noticed that a number of them started wearing UofA sweatshirts to school on a daily basis. When he asked why, they told him that when not wearing the sweatshirts, they were being harassed by campus security people saying they (the women) did not belong on the university campus and that they needed to leave.  There are many more examples. Casual racism, like casual sexism, is unfortunately endemic in our society.
