@StarJo – I really feel for people with coprolalia. You know they have got to be so embarrassed that they can't control their words.
It would be awful to shout out racial slurs every time someone of a different race walked by. Though the person might not actually be racist, just the stereotype popping into their mind at first glance could trigger this.
I had issues with uncontrollable thoughts and fixations when I was younger, but I never had problems with coprolalia. So, I sympathize with the victims of this disorder greatly.
