This topic only really makes sense if you see cis and trans as being immutable properties, and inherently different from each other in some fixed way.
I don't, but perhaps detailed dissection of that view that is food for another thread, which I might start if people are interested?
For here I will perhaps merely observe that breaking out of the fixed "trans" mindset, by means of using a massive self-mindf**k thought experiment, and managing to reach a place where I can switch headspace, virtually at will, to see the world through cis eyes, is something that I am immensely proud of.
That took a lot of time and work. Though ironically I suspect it is something that I am proud of, while both cis and trans would shrug at it, because both groups would be puzzled as to why one might want to be able to do that...
