A lot of the things you mentioned serve as a way to keep the status quo in place, hence why they are not frowned upon. This extends to animal abuse as well. We abuse and kill trillions of animals on a yearly basis for our palate pleasure, often in horrific ways. But put a thousand pigs with the cognitive ability of a 4 year old in a gas chamber and nobody cares. Put a dog in a gas chamber and you’ll be killed yourself by an angry mob. It’s the hypocrisy and cognitive dissonance to serve the status quo. Animal abuse is highly normal in this society even though we say it is not.

You can also see this in serial killers as well. Serial killers who kill pretty, young white women are highlighted. Serial killers who kill black or trans or gay people or sex workers are often ignored for a very long time or mever found at all. Because this society deems it normal not to care about these victims.
