Sports, in general, is unique in modern culture. Everyone gets to play, with everyone is expected to play by one set of rules, often with referees to impose those rules. Sports also breaks down into individuals, teams and leagues, based on one's level of ability in that sport. Sports does not assume we are all equal, since that is a myth. It has objective criteria such a points scored, or seconds to run 100 meter, to objectively separate talent into leagues. It does not try to cloud reason with sentiment.
Sports acknowledges and takes into account various levels of ability; we are not all equal in sports. It tries to place people with equal ability in the same leagues, so the competition is always fair, allowing everyone at that level, to play at their full potential.
In sports, men and women all play by the same rules, but since men and women are not physically the same, having two leagues; men and women, allows the games to be fair and allows everyone to play at their full potential; for the glory of sports and yourself. If you try to force all levels of ability to play together, the best players get bored, and the worse player get frustrated, since the idea that we are all equal is an illusion. Sports is objective reality in a microcosm.
In the news, the Liberal created biological males doped up to look like women, are wanting to play in women's sports based on the shallow Liberal philosophy that what counts is on the surface; if it looks like a girl it must be a girl, but not what is deep down like in sports; biology, physicality, talent and skill level.
Ironically, women; feminists movement, once benefitted by the faulty premise; superficial criteria before talent, i.e, quota system to make it equal? However, women in sports have awaken to the benefits that objective segregation by ability brings via sports; glory of sports. I think the pendulum is about to swing the other way, away from dual standards caused by shallow thinking, back to common sense culture, that can teach everyone to play the sports of life, by one set of rules, with each in our own leagues, pushing our individual ability.
