Tell them to buzz off (or worse language). I don't think spirits care a hoot about our language. Yes, they might care about our intentions, about anger overcoming us--and give us some guidance in that direction.
But to be your school marms, preventing you from "bad language" sounds more like some over-zealous spirits who don't understand the underlying reasons for the "rules".
And "protecting" you from communication with other spirits sounds more like interference than help. Even guides with our highest and best development in mind--allow us to make our own decisions. That IS in our best interest.
For my money, these spirits don't sound like they are really "guarding" you. They are interfering with you--IMHO.
But ultimately, this decision too is your own.
