He has covered a lot of ground there.
Clever to concentrate on two women in one sport - Serena and Martina. Both very popular with the public and tennis is popular in this country. It puts the human faces onto the issue.
Morgan shows exactly what would happen if men are allowed to switch to women's tennis. Lays it all out there. Easy process for the man (and of course he can choose to identify as male again after his tennis career); devastation for the women.
Morgan then links to other instances in other sports (cycling, athletics and volleyball) where biological males are already winning women's titles, so it blows the "miniscule minority" and "would never happen" stuff out the water.
Ends with his support for Martina for talking sense. He's publicly supporting a lesbian so that will head off a bit of the LGBT backlash. A lot of lesbians (the female sort) will agree with him.
