It's a superb statement.
And I think the comments she has made about Bridges are helpful and useful. It's very easy to make it personal with athletes such as Bridges, Thomas and Hubbard, but actually, Kate's statement is correct. Those athletes were invited to take part in the category. Yes, they could have refused, but it would take an extraordinary amount of, something.. integrity, determination? to refuse a spot that is being offered to them. If I found a legal way to get a place at the Olympics, would I decline to take it (unlikely in my case unless a new category of cake eating is brought in)?
And focusing on individual athletes does lead to shouts of 'transphobia' which does nothing to help fight our corner. It's the systems that are in place that are wrong, and Kate is correctly identifying that.
