You seem to determined to see racists everywhere. My opinion is that shaming on social media is wrong and, like vigilantism, can have unexpected consequences - including increasing racism. This doesn't mean we don't call out racism but it does mean that we don't try and burn people at the stake because we think we are automatically on the side of the righteous. That way madness lies
So what was the alternative here? Should he have tried to report her to the police for time wasting? I think we both know exactly how far he would have got with that.
Should he have shrugged, accepted her racist tirade, and then let it go, leaving her feeling empowered by the fact that she used state brutality to threaten and intimidate a black man and got away with it?
Or should he make it public, so that this woman faces consequences for her actions and will never attempt this again? And so that other women who might have tried this think twice about what they have to lose before doing so?
I don’t see any basis for criticising him for going for the third option. Of course it’s wrong if the woman receives death threats and if any are made the perpetrators should be punished. But he doesn’t owe it to her to protect her from the consequences of her own actions by allowing her threats to him and to other African Americans to go unchallenged.
The reality is, virtually nothing has been so effective at challenging the institutionalised racism in America as video evidence of the treatment African Americans and other people of colour have faced. Without footage of the murders of Ahmaud Arbery and Botham Jean, justice would certainly not have been done. Without footage of countless unjustified traffic stops, police searches and racially motivated attacks people in America would still have the option of putting their fingers in their ears and pretending the problem doesn’t exist.
It makes life much more comfortable for the perpetrators of racism if we all decide that sharing footage of their behaviour is wrong and ‘part of the problem’ but it’s actually a hugely powerful agent for change and one of the most effective ways in which black voices are actually being heard in America.
