Self-determination never meant that we could re-write biology to suit our preferences.
Biology isn't being rewritten for trans people any more than it was rewritten for women. The justification for self determination was psychological interchangeability. Both women & trans people have been accused of lacking legitimacy in these areas.
I can't figure out what you mean by the underlined sentences. What is "psychological interchangeability"?
There's a reason why MRA blame feminism for the increased visibility of trans gender people because they believe feminism opened the door to their legitimacy when they claimed interchangeability with men…& they would be partly right.
You cannot expect anyone to take seriously an argument that quotes the so-logic of men's rights activists.
What it means is that, when it comes to the choices we are all free to make - such as what work we will do, or what hobbies we will pursue, or who we will love, or where we will live, or what clothes we will wear, or how we will vote - our sex should not dictate the options available to us.
Yes & trans people have been discriminated against in similar ways in terms of access to employment, housing, health care, public utilities, safety etc. Like women protections from discrimination have been written into law & like women inequalities still persist on many levels despite the law.
Many groups are discriminated against in ways similar to the ways women have been and still are discriminated against. Disabled people, for instance.Trans identified people share many experiences with the disabled community. That doesn't mean trans identified people are disabled.
Nobody except fringe fascist nutters think trans identified people should be deprived of their civic, legal or human rights just because they choose to live as the opposite sex. Laws exist to protect them against such discrimination, and those laws need to be enforced.
