I understand the OP to be saying that because therapists present the best, professionalised side of themselves - don't show up with their neuroses, aversions, judgments etc. - therefore their side of the therapeutic relationship is fraudulent.

On the one hand I think this is inevitable and not problematic - it is good for therapists to be on their best behaviour, not put the self first etc. when they are at work. And of course almost everybody does this at work, but it doesn't necessarily make every relationship taking place at work fraudulent.

On the other hand I kind of get where you are coming fromBudfox - I think - in that the therapeutic relationship is incredibly personal for the client, much more so than for the therapist, and on the clients side it involves the kinds of letting down of barriers that usually only happens in very close relationships e.g. romantic relationships. And yet it is not reciprocal for the therapist and they are not letting down all of their personal barriers to the same extent as the client. I think this is necessary, and if it were not so it would be very unethical (paying a therapist for a relationship where the therapist is gratifying themself, not necessarily putting the client first, etc.) But I do see how it can seem fraudulent - it's kind of mimicking a close personal relationship, but it's not so close or personal for the therapist.
