1. Simply don't accept a job if you don't want to take it.  There's no way to prove your reasons for declining a job.  

2. Women and girls want their privacy? Is that a joke? Women and girls are giving up
Their privacy on Facebook on a national scale.  

Do you know in many places including Europe a lot of bathroom/changing rooms are shared between both sexes.  

No one is peeking over the stall at you; similarly no one is peeking over the stall at you here either.  Do you really believe that a man/boy who identifies as a woman and is wearing women's clothes is really trying to do anything other than pee in peace? 

Exactly how do you explain to your daughter that there's someone who looks like a man in the restroom with her since that's your gripe? If they changed their sex then what? Your child's free to see a freshly grown penis from a clitoris? That's why this change doesn't make sense no one wants to breach your privacy they just want to use the restroom without being looked at.
