To be fair, that's literally every American company though, and many foreign ones too. You find me one that didn't at least put out a boilerplate statement about "black lives mattering" back in May-June 2020. The lefty activist pressure that "silence is violence" was enormous, and tepid minimum effort press releases shut them up and got them focusing on their next target to demand "speak up," so it was probably seen as worth doing for a lot of businesses that were probably apathetic about U.S. politics in general.
But Ben & Jerry's is 100% anti-white and terrible regardless of that.
B&J were supporting BLM as far back as 2016, so I haven’t touched them in at least 5 years.
