I don’t see how entrusting the process to the IOC will ensure that there’s less transphobia behind the decision. It’s not exactly known for being very progressive :p

And either way, I don’t think fighting to push something through against the popular will, without a clear plan for consensus-building afterwards, is a good way of building lasting change - I’d say it is a good way of creating a backlash, and of selling the Conservative image of the trans movement as anti-democratic and elitist.
