There is no argument, those who want males competing against females in female sports simply don't care about safety or competitive disadvantage so none of these arguments matter.

They simply want to believe that feeling like a different gender makes it so. Why ? Your guess is as good as mine.

When you realize that, you realize there is no point talking to them it's a flat out waste of time. I don't try to debate this anymore, I just assume you lack any sense and get as far away as I can.
