To put it simply: the issue is you say "having trans-women in sports is unfair to cis-women" and cite (and I'm using that term liberally) anecdote to prove your case, but when someone actually studies the differences they don't appear. Now it's possible that marathon racing is special, but I think you would have to demonstrate that. 

Hold up are you saying now that everything said in this discussion in this entire thread is backed up with a citation? That is rediculous. We have not gone into the validity of Sundin's citation either. What are you doing here Torillian?

I've read Sundin's citation before, as someone vaguely related to the field I get these things as email updates when something interesting is posted in the journal Science. 

I'm here because I'm curious if you have any studies that would go against what Sundin has posted because I've read that before and I could think of reasons it may not apply to other sports but it's pretty convincing on its own without other studies to show its faults. Opinions and vague ideas of what could happen to sports is fine, but if you want to make policy that should be based off hard evidence and as little conjecture as possible. So far it seems that marathon running can move forward without making any special categorization of trans athletes. I'd be interested to see how this applies to other sports.

Response to your edit: Well if you're talking about people just saying "I'm a girl now" and jumping into women's sports then we can just make a rule against that. It's a boring question.
