No one is arguing for the hypothetical that if you’re somehow linked to a nazi by an infinite number of degrees of separation you’re literally a nazi, as that would make the term nazi, calling people out, and so on, useless. Read it in the only way it makes sense: those with the most power, such as big businesses, platform owners, politicians, and so on, have the responsibility not to platform them, definitely not to fund them, not to normalize them, not to launder their ideas or their acts. And regular people like me or (I assume) you, we still have a responsibility not to tolerate nazis. We have a responsibility to call these people out, to protest, to defend those who are marginalized the most, to organize and stop the worst from happening. Because our politicians sure as hell won’t stop them, and big corporations are already showing their hand.
