Mainly, her dedication to the conservative beliefs in American politics which largely defy Transgender people.
Now, she's gone and angered her 'fans' some more, by posting an insensitive joke on her Instagram, which blatantly pokes fun at Transgender people.
Posing with Aerosmith lead singer Steven Tyler, her caption read, "@iamstevent and I are working on our duet for Dude Looks Like a Lady. One of my favourite songs!"
It's a reference to one of the bands most famous songs, but the joke makes negative connotations towards trans women.
It comes only a couple of days after Caitlyn confronted talk show host Jimmy Kimmel, for making insensitive transgender jokes while she was coming out.
Ah, the irony.
