No. The men who are any good aren't moving. Its those who are genuinely confused and thosd who aren't good enough for fair competition but realize that mediocre to poor male athletes can out power the best girls who are switching over.Well if all the guys go over to girls sport to dominate that'll leave a void in men's sports so all the women can go over there and dominate. Pretty soon it'll hit equilibrium and then they'll start crossing the line back to normal.
Right?
The NCAA just endorsed the practice. You really think guys if mediocre talent wouldn't wear skirts to rake in full scholarships?You're not going to see very many men "switching over". Most major sports (e.g. Olympics) have a testosterone limit for female athletes, so a man would have to seriously dope up to get under the limit.
Then, if you're doing it as a professional, women's sports don't pay anywhere near as much as men's; being mediocre in a men's league is more profitable than dominating a women's league.
And finally, better than half the world would hate you; some would call you brave and stunning, but that's a minority.
So, it will continue to be a small lightning rod of confused individuals that also happen to be at sports. I figure if you're confused enough to have gender dysphoria, then you're confused enough to think that women's sports is good idea.
