Here is one of her blog posts expressing frustration, although still vague: http://julieannhorvath.com/2013/03/22/there-is-no-emoji-for-...
going by that post it seems that for some reason she thinks it is appropriate to use the word "Fuck" on stage and inappropriate for people to complain about it. That seems a little backwards to me.
The whole of: When men cuss on stage, they're commanding. When women cuss on stage, they're unprofessional.
