I've stated where I stand on the pronouns debate in a previous thread and I suggest you read it as your understanding of trans people from a teacher's perspective is worrying and is clearly cherry picked from Twitter extremists.

Secondly, if it was as easy as "why don't you just live your lives as Women and stop complaining" it would be a non issue, for trans people the journey is very personal and they'd love nothing more than to just be left to get on with it. But when something as simple as going to the toilet is questioned then it becomes an issue.

Have you ever been to an event? Out for the evening? Gone somewhere on holiday and needed the toilet? Of course you have.
Try this for me, next time you do try not using any public restrooms, this means your only toilet is that you use at home. If you've ever come close to wetting yourself over something so trivial then you'd understand the plight many trans Women have. To be within inches of degrading yourself in front of friends, loved ones. To be in floods of tears because you're bent over double trying to keep it in. Is that living a life of normality to you?
And don't even get me started on going without food because the dysphoria prohibits you from ever leaving your house. No quick trips to the supermarket. You'd rather starve than face reality. Try that one too, going without food for a good week, seeing what scraps you can scavenge.
Better yet, stick a dress on and go out, see what sort of looks and comments you get. Until you've done all of these then you know nothing of what it's like to be a trans Woman and have no place to tell them to just "live with it, because the gays did" a statement which also shows a worrying lack of understanding of the whole LGBTQ community as a whole.
