This is actually a perfect example of this! Let's take a minute here to look at your response.
"Do you have hard data to back that up"
I literally said "I've found". Folks who go on long winded discussions about privilege do exactly this - redirect, misunderstand, demand impossible things.
I didn't say I had hard data, I said this was just my personal experience. I don't need hard data to back up my own experience - it's simply my experience.
The "hard data" that you seem interested in is often horrendously weak in this social studies type area. This may be offensive or triggering, but measuring job performance is extremely hard, and measuring it relative to communication styles is harder. This raises a question in my mind, are you unable to evaluate the likelihood that hard data would exist so that it makes sense to demand it and you would believe what I presented if I found some? There may be some poor critical reasoning skills here.
"just anecdotal personal bristling whenever someone says "privilege""
Dismissing others experience rather than engaging on the comment. Is your experience positive with folks who communicate like this? Mine is not. The writer is using this over the top over formal language. Their language choice is all a bad sign of ego ego ego. Tech folks are in high demand, they are not gods.
"While I very much appreciate the fact that exceptionally talented and engaged recruiters reach out consistently"... "I will be unavailable for further discussion."
