However, even in respect to their 'chosen' identity,

I think there should be restrictions,

 

such as exploiting sports.

If a transgendered person (male to female) lived most of his life as a male and benefited from the hormones until that transition,

their bone structure and muscle mass is different.

Why should they be allowed to compete in the woman's division?

 

Same idea with people trying to exploit the law.

Biology is undeniable in this sense.
