"It’s Not Up to Cis People to Define Trans Women’s Experiences"
It's not up to anyone else to define me or my experiences. It's not up to anyone else to rewrite my past or say that my reality is false. It's not up to anyone else to dictate my observations from my experience. It's not up to anyone else to tell me what to think and how to think.
My past is I had a brother not a sister. I grew up having that experience and others treating me as having a brother. My identity was formed and framed in a collective way - identity is not decided purely by individuals, it is also a collective thing.
en.m.wikipedia.org/wiki/Identity_formation
Identities are formed on many levels, micro, meso, macro, and global. The micro level is self definition and relationship to people and issues as seen from a person or individual perspective. The meso level is where our identifies are viewed, formed, and questioned from our immediate communities and/or our families. Macro are the connections among and between individuals, issues, and groups as a view from a national perspective. Lastly, the global level is connections among and between individuals, issues, and groups from a worldwide perspective.
It is harmful to merely ignore the effect of individual identity being forced onto others. However it is done it has unintended consequences which can disrupt the identity of others, which in some cases can be harmful.
The most obvious example of this is the effect of a married man with children transitioning 'to a woman' and the woman is expected to identify as a lesbian and the children to refer to the father as 'Mum'.
The transwomans experience should not override the experience of those around them, nor should it dismiss the experience that a close relative has if a family member transitions because it also has an affect on the identity, freedom and emotional security / stability / self confidence of those closest to them.
The whole idea that women shouldn't define the experience of transwomen is based on the myth that the process of transition is a neutral one without real life effect on others.
This fallacy is why you cant just trot out this tripe without thinking.
The individual does not live in a vacuum. The individual has a family unit and community too and identity is relevant to multiple groups in different ways. It is multi level and complex, not simplistic and narcissistic.
