I find is so bizarre that anyone who disagrees with this stuff is presumed to be male and childless, as if other women who disagree don't have a right to their own opinions on this, or must automatically be wrong, not worth arguing with, or confused.
These threads just go on and on and on. It's tedious. If anyone could actually provide real statistics about the actual number of teenage boys/men who are thinking to themselves "gee, you know how I could make it in the sporting world? I'll pretend to be female. Beat them all. That's the way to do it", I'd be fascinated to see it. People don't declare themselves to be trans for a laugh, they do so after long fought internal battles, knowing they don't feel right in the body they were born with. Rates of trans-related suicides are horrendous - it's not something that any average person would do, with all the bigotry and prejudice and misery they'd face, without feeling it was their only choice to be able to survive.
This is getting to the point where you all sound like bitter conspiracy theorists, clinging on to isolated incidents of issues that have absolutely no semblance of the vast majority of people identifying as trans, who pose no more threat to anyone than you or I.
So yes, if my daughter was playing sports and a trans female wanted to participate, it wouldn't even register as a blip on my radar, other than to think I was happy that that person was able to be who they really are.
