I don't think anyone would bother to march. This is pretty small stuff.You KNOW if he was asked to take down a Rainbow-Trans-BLM flag there would be a HUGE backlash with people marching on the school,media slut polticians (WONG) on tv denouncing the school etc.
OTOH, the rainbow and trans flags are pretty accepted in this country and are no longer controversial - except perhaps w the 5% of people who vote PPC. So "false equivalency" here. The rainbow flag has been accepted and mainstream for 20 years or more. Not sure about BLM in this country.
