I'll risk the downvotes then.
> A lack of diversity is just a piece of data: it might be complete coincidence, or it might be related to some underlying bias or discrimination.
I say it's a coincidence. I've known racist people but they were an overwhelming minority and had no power. Let's stop there. Find me a systemic racist in a position of power where I work or participate in local events and I promise I'll fight to eject them from their place of power. Done. Discussion should be over at this point: let's have actionable steps. We don't have them? Let's do something else.
"Might be related to some underlying bias or discrimination" is not a convincing thing to say. Going witch-hunting for witches that are 90% likely to not even exist is unproductive. The Sun's magnetic storms might influence our moods, that too falls in the "it might" category, but I don't base my life decisions on it.
> "Calling out" a lack of diversity is just bringing attention to that piece of data
A lot of people have been "bringing up attention" to many things. What are you doing to help? I had a few technical talks held in my city and in one occasion I insisted the discussion after the talk be in English and not my native tongue because we had just two English-speaking participants in the audience. I am helping in practical terms. Are you helping practically?
Many people in more privileged countries are completely blind to the fact that "raising awareness" is being done ever since the 1970s yet very little progress has been made in many areas (happily racism and sexism were reduced, which is good!). When are you going to understand that somebody at one point should actively do something about the problems and stop "raising awareness" until the heat death of the Universe?
Many people are quite aware of a ton of problems, believe me. I go outside and talk to people of many nationalities and races. The people willing to do something outside virtue-signalling are very few and far between though, sadly. And you strike me as a virtue-signaller.
I realize my tone is a bit combative but honestly, it's getting tiring and at one point I find it hard to talk entirely calmly when the other side of the discussion is content to only repeat the same things like a broken record.
