The animal activist group People for the Ethical Treatment of Animals (PETA) is urging the public to stop using animal names as verbal insults to other humans because it is “supremacist language.”

For example, the group said if you want to insult someone for their lack of bravery, call them a “coward” instead of a “chicken” because the term is demeaning to chickens.

“Words can create a more inclusive world or perpetuate oppression. Calling someone an animal as an insult reinforces the myth that humans are superior to other animals & justified in violating them,” PETA added in the tweet. “Stand up for justice by rejecting supremacist language.”

The organization also continued with a string of tweets, with one saying that “anti-animal slurs degrade animals by applying negative human traits to certain species.”

It went on to denounce speciesist language in another tweet as “harmful and inaccurate,” describing pigs instead as “intelligent” and snakes as “clever.”

This is the latest of PETA’s activism campaigns that have tried to stir up controversy. Not too long ago, PETA released video footage from “Gobbler’s Rest” at Virginia Tech to claim that President Donald Trump’s pardoned turkeys are living in squalid conditions.
