That would be my guess and on one hand totally understandable. But if you claim to be against racism and systemic racism, and want to fight to end it, doesn’t supporting the NFL belie that claim? Essentially you aren’t willing to sacrifice something you enjoy for their greater good/fight.
When you find somebody who is pure in what they support let me know.
You gotta pick your battles. To me, cancel culture is all about capitalism. If enough people dislike a practice or an idea and get organized about it, they can change it, using capitalism. I’m OK with that. If you don’t like with the Seuss corporation did with those 6 books, Make some money and buy the rights, publish it yourself.
As long as the government is not picking the winners and losers, it sits well with me.
