How can a person who has gone through male puberty be a 'cis woman'?
And if you genuinely believe that this is a 'far right' issue, then you have not been listening to the vast number of socialist and left wing feminists who have been campaigning on this very issue. Or perhaps you misunderstood because you thought it was about a different group of male people?
Either way, feminists have been fighting for the following for a very long time now:
That sports be protected to be fair and safe for female athletes.
This means that any male athlete that has been found to have gone through any degree of male puberty should be excluded. Because those male athletes have a physical advantage that is never going to be available to female athletes.
This means all male athletes with pubertal advantage whatever 'gender' they identify as and includes those who have a male difference of sex development that includes those males having testes (visible externally or not) and are producing and processing testosterone.
At the moment, athletes who are male with a difference of sex development that means their bodies do not produce or process testosterone at all are included in the female category.
This has always been the basis of feminist campaigns around this issue. This is the 'centre'. It is solely based on the principle of what happens when you allow male athletes to compete in the female category when they have any degree of virilisation.
Including those male athletes discriminates illegitimately against female athletes because it violates those female athletes' needs and rights to safe and fair competition. PLUS it actively removes the equal opportunity for those female athletes to achieve their full potential and all the opportunities that gives them.
I am confused as to why you have positioned this as being 'far right'?
Sports are won on on bodies. We cannot base discrimination legitimately on emotions and emotional histories.
There is inclusion. And then there is male inclusion that simply continues the discrimination, and oppression, of female people.
