That is a very simplistic understanding of the reality of the world out there - and the evidence is all over twitter and elsewhere...
A 'trans person' is simply a person of one sex pretending to be the other sex. As has been demonstrated on here so many times - it is not possible to transition biologically, nor is it possible to transition your gender (you simply expand the stereotype of your original gender). Therefore there is technically no such thing as someone who has / can / will transition...
That leaves only those who want to transition - who having an illogical desire in the face of the evidence of reality must mean something else is behind it...
the driver behind it might be gender dysphoria, but equally it could be distorted influence from elsewhere (e.g. caught up in the lies and deceptions taught online to many vulnerable people), it could be a sexual perversion, it could simply be a form of toxicity and power - loving watching others being uncomfortable - esp. in the toxic male rejoicing in the discomfort of the vulnerable female - in other places it might be a belief that you will have better conditions in a women's prison than a man's prison... etc.
There are many reasons why a man might pretend to be a woman, a minority of those reasons need sympathetic treatment - at the other end of the scale they might require a prison sentence...
There are also plenty of men calling themselves 'women' or 'trans' who have zero interest in looking like a woman - full on beards / often dishevelled men in a frock - they clearly do not have gender dysphoria!
and still...
it is irrelevant
a trans woman is a man
men are not allowed in women's spaces!
