No. My argument is when two marginalised groups are in opposition, then it’s prudent to listen to both sides of the argument. Otherwise you’ll end up with a mess.
In this argument both sides have a valid claim about their treatment at the hands of the other, and the issue is complicated. It is very easy to pick a side and declare the other to be acting in bad faith, but the answers aren’t that simple.
This needs to be answered on a sport by sport basis, and it needs to be answered fairly. If there are notable advantages to trans-women athletes by virtue of their birth-sex, then exclusion isn’t ‘transphobia’ - it is fairness. Id there aren’t any advantages, then their exclusion is discriminatory. We don’t have the answers yet, and so we have to tread carefully.
