If their prices go up, then you should stop shopping there—otherwise you are subsidizing BLM.
Their prices have been reasonable.
Actually their headquarters management in California are more on the conservative side. The store in Seattle that I shop at has roughly 80% good hardworking clerks and 20% BLM/Antifa types from the local colleges where they likely get indoctrinated by Marxists, systemic racism, climate change, social justice, etc.
