Completely agreed. So long as I get to define what is bigotry, and what is valid grievance.
I don’t think this is a causal relationship. Just think about the trillions of acts of bigotry that take place each year and how few of them result in genocide. Bigotry is bad, genocide is super duper bad. But saying one leads to the other needs to be qualified that it’s like a one in a billion chance. Equating bigotry with genocide debases the severity of genocide and is like saying unkindness leads to genocide. Or that not saying “bless you” leads to a feedback loop that ends in murder.
For the sakes of what are nearly always incredibly low value and tedious "debates" I'm fairly ambivalent on defaulting towards removing hate speech. We can get enough of it from our government and media in the UK anyway so it's clearly not under any real threat.
