I absolutely abhor the words transsexual, transitioned, transitioning, transwomen, transman and even transgender to a certain degree and any other labels that are used including cis, trans, gid and their variants. Why you may ask?
As for for the word transsexual and its variants, to me they are derogatory terms. I did not change my sex. (yes I'm aware of my biological nature) because, I have always been a female. When one has the knowledge of what is going on one has understanding. When I found out about this term 35 years ago. I hated it then and I still do. My doctors and surgeon at the time used it. However, I was naive at the time and did not correct them.
The words transitioned or transitioning, do not apply to me because I never transitioned period. I just had surgery so that I could function as any normal female should.
Take the word transgender. I did not change my gender. Again I have always been a female. I have used this term only once in describing myself in over 22 years and that was in relation to my current doctor, so that any medical issues are treated in the context of my medical condition.
As for the other words, they are just labels that others are creating to use instead of the 'trans' what ever variant that seems to be the flavour of the moment.
I will not support anyone in the usage of these words in relation to me or others. However, I will defend your right to use them.
Kind regards
