The historical context is not the same. The watermelon stereotype is an anti-black racist trope from the 1800s that arose from resentment against newly emancipated former slaves. It accused black people of being “happy to do nothing but eat watermelon”. In comparison, the stereotype of white girls enjoying pumpkin spice doesn’t have the same negative connotation.
That’s disingenuous. The 911 operator, who works for the police department, obviously knows the name of the sheriff. Any police department flags calls from police officers, including non-emergency calls. The sheriff should have known better than to waste public resources to strongarm a business when he could have simply emailed a complaint to corporate.
