USGA and R&A have aligned on a protocol for this that enables people to compete in identifying gender once they meet certain criteria. Looking to follow principles that have been adopted across many other sports, e.g. rugby where it could be dangerous.
I’m not sure how’s it’s aligned though. For example let’s take Caitlyn Jenner, a previous male Olympic athlete which has transitioned and very openly. Arguably she was a very strong male athlete pre trans and if a golfer would have a very clear strength advantage of playing from the red tees against other women. On the flip if she was asked to play off the yellows or whites it would be discrimination. The same could be said if she competed in womens boxing, weight lifting etc.
The above are extreme and precise situations, but as I said I it definitely opens up muddy waters. I honestly feel with the gender fluid/neutral approach, tees should not be labelled as male or female, but we should label them as colours and the give them the appropriate SI. As this becomes more common you will have pre trans men playing off forward tee’s which could be deemed and advantage and pre trans women playing from whites which could be seen as a disadvantage. I would keep them labelled and allow the handicaps to work the difference out of a period of time.
