The initiative you're being dismissive of is what emerged from "find out why that is and tackle _that_ problem". There are systemic barriers in place, which are being ignored because it makes the discussion uncomfortable. That's the purpose of promotional groups. They exist to point out those things and help us move past it. Forget tech for a moment and consider any other civil rights that we take for granted today that we wouldn't have x years ago.

If addressing it causes "resentment and push-back" consider reflecting on your own biases first. It is very likely the issue is there.
