The butterfly is usually used in connection to 'monarch' programming - trauma based mind control. It may also have pedo connections, and sometimes these are just very strange synchronicities. I would not put it out of the realm of possibility that there is more to J.K. Rowling. Though I love her books, I've seen the patterns repeat of politicians and media figures who are the most over the top fanatical Trump haters, who also seem connected to it... no reason to condemn Rowling without more information.
