I think it might be more helpful to say something along the lines of "It's not something that I would personally find helpful to do with my therapist."
I try to speak from my own experience or bring up concerns that occur to me, or even make suggestions, but not tell other people what they should or shouldn't do (except in extreme circumstances when it's something really obviously dangerous).

I think there's enough self-shaming and self-judgement among members here (at least speaking for myself) that a comment calling something that other people find beneficial and constructive "****" is probably going to be hurtful, possibly to OP, and also possibly to the many members reading this who have done exactly this same thing with our Ts.
