I totally understand that Austin's livelihood is on the line here, and I totally get the attempts at all of these competitors to make the strongest possible case for inclusion within the sporting category that's most advantageous to their chances of success.
The fact is that there are dozens of plausible reasons why the likes of Ms Ivy and Bridges should be allowed to compete against women, and it's totally understandable why they would want to emphasise these reasons when they speak on the subject, whilst glossing over/overlooking the dozens of plausible reasons [which, as I'm sure will become ever clearer with the benefit of hindsight, are on balance a lot stronger] why they should not.
It's up the 'powers that be' to take all points of view, most of them made by vested interests one way or another, into account in reaching a balance decision. It does look as if most sporting bodies' decision making seems to be headed in more or less the right decision.
