I was thinking about it, like why there are separate competitions in chess or cybersport or like you said shooting. Can't say for sure, but probably it is because tournament is a tip of the iceberg of what contenders are actually competing in.

For non physically demanding sports most of the work is in training prior to this competition: being able to find good coach, stick to regime, balance life vs sport, emotional control, managing finances and sponsorships, chances of getting into the sport in the first place etc. These aspects are quite different for men and women, so they naturally have separated tournaments.

As far as I know about chess, there are no men-only tournaments in chess. Instead everyone, both men and women, can compete in the "usual" tournaments. But because there are so few female chess players around, to encourage girls and women to play chess women-only competitions were introduced. Some think that such women-only tournaments work as intended by promoting chess among females, some don't. Famously arguably the strongest female chess player in history Judit Polgár never competed in the women's world championship.

IMHO it should be the same in sports. This would also make it easier conceptually to prevent trans women from competing with other women iff they have an unfair advantage, as the other category woul not be marked as men only.
