There are plenty of gyms that are mixed sex - they can go to them.
There are lots of places that aren’t wheelchair accessible, there are lots of places that aren’t autism, blind, dwarfism etc accessible - it would be great if every single place was fully inclusive but it’s simply not possible.
These people are biologically 1 sex.
They are choosing to portray another gender - fine, but with that comes issues such as this one.
You can’t have your cake and eat it too.
I wonder how many people would choose to portray another gender if it meant they also receive lower pay, fewer job opportunities, fewer leadership roles etc.
Imagine being disabled and going your entire life being restricted with things like the gym and then hearing a story like this.
I am not anti trans and anyone can identify with whatever gender they want to but you are and will always be the sex you were born.
That’s not offensive, that is just scientific facts.
