Totally and especially in systemic ways. I see it first hand in downtown Calgary working nightshift, anecdotal speaking, an extremely disproportionate amount of people battling homelessness and addiction seem to be indigenous

From all accounts Jadon is a fairly conservative guy, so I hope he takes this criticism well: but you don't play on their terms.
Which means you don't claim that systemic racism exists against anybody other than whites, because you can't point to a single system which is racist in this way (which seems a pretty first-principles sort of approach).
While the second half of his tweet is pretty accurate, that doesn't even remotely tie into the first half. Personal failings tied to the reliance on a 20,000 year behind-the-times culture combined with a genetic inability to handle alcohol can equally explain what you're seeing on Calgary's streets. It's a less comfortable conclusion since it doesn't allow for white self-flagellation on an industrial scale, but it actually has more evidence in its favour than what Jadon and Melissa are talking about.
