It rubs me the wrong way because it originates in that awful book, I forget the name of it, but it's for people who experienced CSA. I take exception to the idea that saying that somebody sexually abused me is speaking MY truth. The MY part is what bothers me. There is no such thing as a "my truth." There are sometimes different perceptions and different opinions, but then the expression should be "my opinion" or "my perception," not "my truth" as if a "truth" where I was not the victim of CSA can also exist.

But again, I mostly take exception to the phrase because of its origins and to the idea that saying I was sexually abused is speaking my truth instead of speaking THE truth. Reminds me of so-called "alternative facts."
