Look under your name in the post where it reads "replying to". That's who the post is replying to. It's a little different than other social media sites but you get used to it.
You're preaching to the choir regarding men in women's sports. None of us disagree with you, but you're addressing us like we are leftists or Republicans (also leftists). This is a group of generally National Socialists, Fascists or other flavors of nationalists. It would be good to drop the attitude and realize the company you are in here agree with you on most things. If you're unable to understand nuance, I'd suggest going to spinster.xyz instead where you can flick your bean about men with the other cat ladies.
