Someone on the first page asked for scientific journal studies. Well, here's an
open access article on the issue in question.
Sport and Transgender People: A Systematic Review of the Literature Relating to Sport Participation and Competitive Sport Policies
I can certainly understand why people might as a gut reaction feel that there's some kind of potential for unfairness here. And I can understand why someone who is most certainly
not transphobic in general might still have this kind of
initial gut reaction. But, as I myself found out a few years ago after I was prompted by two transgender friends to actually go and look at the research on this topic, those initial gut reactions simply aren't supported by any of the available data. For some, it may simply be a manifestation of sub-conscious biases that we might not even realize we still have. Subtle feelings of discomfort that, once we become aware we have them and of our own ignorance, we're able to recognize are
wrong and can work to address. Hopefully posting that systematic review article will help give a few people reading this that first push of awareness.
This move by the Trump administration combines two of their favourite things. Discriminating against minority groups who they can demonize, and ignoring any statistics or scientific evidence that they find inconvenient. Just like other examples of Trump admin bigotry, they're able to get away with it because so many people out there simply don't question their own biases and assumptions. The execution is different, but "Trans athletes are here to steal your medals" is really just another play along the lines of "Mexicans are here to steal your jobs". They're positioning a minority group who their base has biases against as an enemy with an unfair advantage, who is taking something that "rightfully" belongs to others. With the implication of course that these others who are forced to "suffer unfair competition" are part of the same group as the person the message is being targeted at. It's disgusting and disgraceful, and we should all be giving our support to the trans community over these bigoted policies.
