She seems to feel that if you show yourself fully committed to transgenderism/transsexualism by having bits cut off, you're somehow proving genuine woman-ness and can compete.
I agree MN is moving through the same phase of understanding the issues that many here have done.
The trouble is, no matter what modifications a man may choose to make to his body it does not make him a woman. A woman is not a man with breasts and genitals cut off, a woman is a specific biological entity and you either are or are not born one. There is no way to become one.
Women's sports are for the biological entity group of women. If a man chooses to alter his body for personal reasons that is wholly his prerogative, but losing strength/muscle doesn't mean that person should move down to the women's group - it is for women, not for weakened people. If a line is drawn as to at what point enough alterations have been made to a man's body that he should be allowed to call himself a woman, then you're saying that it's possible for a man to have a legal fiction of being a woman in certain circumstances. As we've seen, there are men who will then force those 'circumstances' from 'total SRS' to 'saying the magic words on a Tuesday'. And women are fucked.
Men cannot be women. It is not possible. No matter what the circumstances, no matter what the needs of the man, this is not a situation for 'inclusion'. Lying doesn't create new facts.
