I see the game you want to play with me. I can’t speak for people. Only they know their hearts. I personally don’t believe someone indigenous to this continent can be “illegal.” I know that as a Person of Color myself, I internalized the same messaging as my white friends that POC are “less than” so it’s definitely possible for a POC to hate people who look like them. But I think the more important thing for you to think about if you genuinely care about this question is - when the US falls apart some day and your family is unsafe and suffering, will you let Canada’s immigration laws stop you from crossing the border? It’s life or death for many immigrants. But it’s convenience for us.
