I think because guys are pound for pound stronger than girls. I've read stories on Reddit years ago by girls who are wrestlers or fighters and get into a playful tussle with some random guy and they describe it as terrifying.

Hot take: Sports are not that important, and it's not the end of the world if someone in the other team is "physically better" than you.

Sports should be just played for fun and for making exercise, not as a profession. And the whole sports industry should be taken down all together. Make all sports amateur and just for the fun of it and suddenly it really doesn't mather who is on your team or in the other team.

Because a man tends to be stronger, faster, and more athletic than a woman of the same weight. It won't work for football, track, or soccer.

"Male" soccer is not restricted to men. Both genders are allowed. There are only men because they outperform women.

edit: Although FIFA forbids women from access to the main World Cup. Also the statement above is true generally, but not everywhere.

Just make an "open class" where any identification, body mods, and performance enhancing drugs are unregulated. The best athletes that science can create.

What sports would it work in? Do you think people will care about the best tennis player that weighs 140 pounds? The best 240 pound soccer players? The fastest 130 pound swimmer? No one wants to watch any of that. It barely works for boxing.

All that aside from the fact that you're still pretty much ruining competitive sports for most cis women by doing it. The reason there's a female "insert sport here" competitive league to begin with is so many women have a reason to compete and can win. A 150 pound trained male athlete will still wipe the floor with a 150 pound female athlete. It's far, far, from just a weight thing. The Williams sisters were the best female tennis players the world knew, and they went out and proved they couldn't beat a man that was ranked over 200th. The world champion austrailian female soccer team couldn't beat a boys highschool team. The fastest woman to ever run the 1500m did it in 3:49. A 5' 9" guy did it in 3:26.

Weight and size is only a little portion of physical differences.

If there's so many Trans athletes, why don't they just have a category of their own?

or why don't we just keep everything as is because it's not a big fucking deal despite what bigots say

if you really wanted to "fix" or "save" womens sport, just start by fucking paying them the same as men and giving women's sport the same attention on tv

Martial arts already has weight classes and gender on top. Weight doesn't cover gender differences

PSA: The preferred term is “transgender people”, not “transgendered people”.

Nobody's making the obvious suggestion to chemically sterilise all athletes.

Yes, splitting teams by sex/gender has never made sense, instead it should be by physical attributes that may or may not happen to align with sex, but irrespective of if they do.

The recent issue with transgender people in sports is manufactured as a tool to spread trans hate. It's a non issue that preys on Americans's sense of fairness.

I'm still a fan of just removing all the rules around drugs and bodies. Let's see what 21st century science can do!

I feel like weight class doesn't do it. Women have higher body fat %. Is a welterweight woman athletically equivalent to a welterweight man? I don't think so.

Testosterone level AND weight. Wait til they find out what happens when you're on hormone blockers.

At a minimum men are born with more muscle fibres and process energy a little more effectively. Puberty is not a factor.

If we could wave a magic wand and make transitions change the multitude of differences it'd be great but the science isn't there yet. We're left with reality.

Weight classes won't cut it unfortunately.

For team sports you can assign a point value to each player and force the team to deploy a maximum total value, like for armies in WH40K

I could see this working better than the current system and would undermine bigots argument about an unfair advantage. Though there are people that think being transgender gives people an advantage in chess somehow.

The purpose is to oppress the queers, logical compromises are not welcome.

I think all athletes should be forced to use large amounts of testosterone to even the playing field. Let's see what the human body is really capable of

Weight is the wrong criteria to use. Why not just have it classed by skill level. Enforce equity in school sports by mandating that a meaningful distribution of skill-based leagues are funded. This seems like a very simple solution to me that would address gender-based inequities in general as well as improve sports overall.
