"Understand, Steve, I'm not arguing in favour of testing based on race; but I'm also in favour of speaking up about facts that might make others uncomfortable."

Hey, I just realised I didn't respond to this. To be clear, I'm not getting upset. I don't think you're arguing for race-based testing. And I wouldn't even be upset if you were. Not least because the idea is idiotic. I'm just trying to get to the root of two things you said.

The first is that I "blew it" in this conversation. I'm still not clear about why you think this.

And the second is I'm trying to make it clear why the comparison of "race" to trans identities doesn't hold any water.

Males outperform females in every sporting discipline (with the exception of ultra-long distance running) from anywhere from around 10% in running events to over 200% in some weight lifting disciplines.

"Some Africans" outperform Europeans by around 1-2% in some sports and are outperformed by those same Europeans or Asians in others. So even if it *were* possible to test people's race in any meaningful sense, it would be pointless to do so.

I'm not sure what uncomfortable facts need to be added to this analysis.
