A friend (cisgender woman) at work showed me something on her phone a week or so ago on a women's forum.
A woman went into a supermarket, and while there decided to use the toilet.  There she met a woman who was a trans woman.  Somewhat fascinated she struck up a conversation with her.
She said nobody had their sense of their own sex diminished, neither saw the other in any state of undress, no privacy invaded, no dignity lost.  She said the person was clearly well-educated and well-spoken.  She then surprised herself by asking the trans woman if she would like a coffee, not usually being so bold as to ask a stranger.  So they had a coffee together, and she enjoyed the conversation with the person being open to her questions.
On the way home, she considered whether she should tell her husband about the experience. She knew that his first question would be, ''did he have a penis''?  Followed by ''did you see it?''  Then followed by the usual male fragile ego question, ''but not as big as mine, right''?  She decided that he would see the encounter as an affront to his dignity, which under challenge would be reframed to him saying that his role is to protect his wife, even though he never goes with her to the supermarket because he might miss something on TV.
She completely understood why men like her husband choose to think of trans women as a danger - it's the opportunity to stick out their chest, puff up and pretend to be the supreme protector, even against hypothetical threats.
