False advertising as art therapist

I have come across people on Facebook or even psychology today in my area that market themselves as art therapists but do not have credentialing... it frustrates me deeply as we have specialized training and work really hard to obtain ATR licensure. I want to "call" these people out and educate on the difference between being an art therapist and utilizing creative expression. I can't decide if I'm coming from an emotion mind and I should just leave it alone or if it's important to advocate. Ugh
