You are right, the male sex cannot get pregnant. I said a female transitioning, so biologically they may still have a womb, therefore scientifically able to be pregnant. Now if you want to call them a woman, I am not debating that. What I would debate is that we allow that person to define themselves. Why would be up to us how to define another person. If I met you and I said I was from Essex but I never felt I was a southerner because I was brought up in the North, would you get all offended that I would dare to not acknowledge my birth place? It is the same and more of a serious emotional point regarding the sex/gender of a person. I do not understand why they feel the way they do but I am willing to accept it, why do you feel that you have to tell that person how they feel inside.
OK that went away from the science a bit but my point stands that biologically they are different to how they feel and what they want/need to be seen as, it is not hard to accept that. It does not change my life or yours one bit.
Thanks for clarifying, it actually makes sense and is a valid argument. I suppose it will depend on what we are saying is 'oppression'. If we are talking about the specific idea of a one gender area/space then I can see why it could mean that some people are made uncomfortable, I am sure that when girls were first officially allowed in the cubs/scouts, etc. it caused some awkwardness about existing ideologies. However, these ideologies adapt and change through time and there are so many caveats to this argument that it is impossible to talk about in a general sense. For example, what is the space designed for, who are the people using the space, how open are they to different people using the space, etc. and more etc..
You say name, this is something else that people change and is an accepting part of society. I get frustrated when people get my name wrong but I doubt my frustration is even a small part of how frustrated people get when they have legally changed their name and people still call them by their old name, whether that is because of a messy divorce, family issues or even, god forbid, a person changing their gender identity (There is another phrase for you to get all upset and angry about).
Biology is one thing but it is not the only thing, as I mentioned it is a fact that I was born in the south but I don't necessarily identify as a southerner, it is fact that I was born there but that does not change my own thoughts and feelings, does it. You must have feelings that may differ from a biological, geographical, societal facts, somebodies gender compared to their biological fact is no different to this.
