Obvioisly someone is still free to respond, and then that won’t be the end of the discussion. So what’s the point of saying it? It seems to escalate the stakes basically: “if you disagree then you are a LABEL!”
By taking a hardline stance, I'm opening the opportunity to prove me wrong. This is an open forum and I'm not calling anyone names for disagreeing with me. In fact if you do have a valid counterargument, PLEASE DO disagree. I'm more concerned about getting to the truth than being right.
But if there isn't a counterargument, then I want my comment to stand out as a stark reminder that we should not accept or be complicit to these types of practices going forward. If we don't take these types of stances, I do not think we will change the culture in tech.
