When it comes to sporting events and transwoman participation in the same, what's in it for society anyway? In other words, we aren't talking about the pickup league at the local Y, where there might be issues, but those issues certainly aren't going to be resolved with hormone tests. We are talking about spectator sports with tickets, admissions, fan bases, etc.
If a transwoman wins a woman's event, isn't the reaction, "Well, duh. What did you expect?"
What are we cheering on in such a case?
When this subject comes up on forums, there are always at least some voices that say, "I hate sports anyway, so who cares?" I think that among the people who are strong advocates of trans-participation in women's sports there are very few sports fans, and very, very, few women's sports fans. I think the supporters of Andraya Yearwood (one of the Connecticut track transgirls) there are an awful lot of people who are inspired by these young people making a tough decision to come out and be recognized, in the face of widespread societal disapproval, but there aren't a lot of people who really think highly of women's track and field as a competitive endeavor.
