If an indigenous person is a sovereignist then voting in a settler election would be a denial of their beliefs.
Absolutely not. They can determine their own beliefs and what is, or is not, a denial of them. That is not up to some white man to instruct them on.
They have the right to vote in federal elections and certainly, regardless of what they want in the future, their communities have needs that they have a right to advocate for at the ballot box. They have every right to reject Canada AND vote in an election for the candidate who would serve their interests the closest. -- Or to decide to boycott if they think that is a stronger message.
They have this right on account of the power of the Canadian state over their land and peoples- whether or not they agree with that power being there.
Your logic suggests that people in Quebec who want a distinct country do not have the right to vote in federal elections either or that people in Northern Ireland do not have a right to vote for a candidate of their choosing in British elections if they do not agree with NI being a part of Britain. They have a right to boycott, elect an MP who will not take a seat, or one who will to support in whatever way possible their view on sessession, or one who will advocate for other political priorities they have.
It. Is. Not. Up. To. You.
Your comment is shockingly paternalistic coming from someone who likes to lecture others about imperialism.
Sean you just built a very very tall straw man. Please stop telling me what I believe. I never fucking said anything about people rights to vote in any elections. I was commenting on the fact that the indigenous sovereignists I know personally have that view.
