electrical grip power due to reliability and long term cost...I've also posted that I believe once puberty is reached, males shouldn't be allowed to compete in women's sports...prior to that, such leagues should be able to decide for themselves whether or not to allow it.
While not a direct analogy, I used to coach basketball in an 'Open League'...i.e. one that accepted "Mainstreaming Downs Syndrome Kids". We drafted one, and he fit in just fine...without any added 'encouragement' from myself or the other coaches (Obviously, Great Parenting), on their own, the kids made sure that the Special Needs kid felt as welcomed as possible...in fact, during one of the first games they arranged a play that cleared out an open long distance shot for him...and he MADE IT!...the whole team and the kid himself were jumping up and down cheering for quite awhile. It's my belief that more Openness...and Kindness are what's needed right now on this 'Trans Issue'...those kids are in serious danger of ideating and carrying out...suicide. Just imagine being a parent and having that happen...those kids didn't ask for this condition...so, let's not make it any worse for them...one man's opinion.
