Seems he was not forced to wrestle against girls only.
He was born female? Seems to me he should be allowed to wrestle as a boy if that's what he wanted. In fact he was: During high school, Beggs also had finishes in boys' division tournaments, including third place in Greco-Roman (3 person bracket) and third in freestyle wrestling at the USA Wrestling Texas State Championships in 2018 (6 person bracket).[9]
I guess I fail to see how he was harmed as he wrestled in both boy's and girl's competitions
