The arguments of supporters are quite simple. Average men are taller, heavier and stronger than women. That is the biological difference. When playing on the same court size, same goal frame, same ball as men, the physical requirement placed on female players is clearly greater than their body structure. Therefore, some opinions suggest that adjusting goal frame size, ball weight or even court size can help the match be more balanced, more suitable for the player's physical condition.
In fact, there have been sports that have been adjusted like that. Women's basketball uses smaller balls. Women's athletics has lower racks. Women's tennis in Grand Slam tournaments competes in 3 sets instead of 5 sets like men. These differences do not make these sports lose value.
But the opposing side also has very thoughtful reasons. Football is a sport with unified rules of play globally. If the size of the field, goal or ball is changed, women's football will become a different version, reducing the feeling.
Another factor is the story of equality. Women's football has gone a very long way to be recognized seriously. Many female players want to prove that they can completely play football under the same rules as men. If the rules are changed just because of gender differences, there are concerns about unintentionally strengthening old prejudices.
The current reality shows that women's football is still developing strongly even though the rules of the game do not change. Women's World Cup recently set many audience records. Professional quality has also increased significantly. Viewers do not seem to watch women's football to find a version that is exactly like men's football. They accept the natural differences of this sport.
Perhaps the most reasonable approach is not to completely reject the idea of change, nor to rush to adjust the rules. Modern sports are always based on data and experimentation. If there are reasonable proposals, they can be tested at the youth level or semi-professional tournaments, and then evaluated by specific data.
