Is it really an attack though? Supporting the status quo (by objecting to discussions about changing it) is the perceived state. Is it an attack, to observe this?
I understand folks feel uncomfortable talking about systemic bias. Especially if they don't suffer from it. But that's exactly the issue of status quo vs change - getting folks to notice/discuss it. So there can be change, which requires the comfortable to change too.
I think it's intended as an attack, but even if it's not it's just a terribly unfair characterization. If you host a meeting to review a design document, and I start talking about the Syrian Civil War in the middle, are you really supporting the status quo when you ask me to stay on topic?
