Hi Richard,
Yes, people should be who they want to but it hasn't always been easy. Today in the UK and Europe at least, it is far easier to transition without any difficulty as there is a lot more understanding, acceptance and legal protection than there was twenty years ago when a lot of us 'older' women would like to have transitioned. Knowing your rights and the routes open to you is a huge step and the internet has helped to open that up.
Now if I could have done all of this before puberty....................
Thankfully, our society is changing positively and it is much more easier times for younger generations than it was in the past. Hopefully, it will keep improing.
