Acknowledging that there are situations where sex matters has always been the definition of feminism. And prioritising male people over the needs of female people as you have just stated, is misogynistic.
Female people are equal to male people in their ability to get things done. However, female people are NOT male people and cannot be treated as just another male person. If you understood this as feminism, then I suggest you will always be proven wrong. Female people need accommodations because of their sexed body. This has always been the case. You seem to have misunderstood the nature of the 'equality' that was sought. It was equality of opportunity. It was NEVER female people being treated as if they were male people. Because that would have been harmful to female people.
For example, female people had very different lifting limits for roles where lifting was needed. It did not mean that female people should be discriminated against for not being able to lift as much as male people, because it was recognised that female people contributed equally to the role, but needed this accommodation. These days, there are now many devices used so that even those with less ability to lift the old maximum weight limits in roles can do so without harm.
This is just one way that female people sought equity, not 'equality' as you are describing.
When it comes to sport, the same equity applies. It is about giving female people the same equal opportunity to achieve their greatest potential, and to win. This cannot, or will very rarely, happen when a female athlete is competing against a male athlete.
Again, this is not Sex Fascism as you have derisively described it on other threads. This is equity based on scientific fact, rather than philosophical theory and belief.
It is not giving female athletes 'equality' to include any athlete who is male in their sporting events. That is giving those male people, who belong to a sub group of male people who may need special accommodations for their own needs, the additional rights of competing in a protected category where that group collectively is known to have a physical advantage.
Treating a sub group of males with pubertal advantage as if they were female people for the application of sport is not EQUAL!
