But that doesn't give you entitlement to impose YOUR beliefs on your therapists. That would be impinging on THEIR boundaries. You have to be willing to respect others' boundaries and, in the least, compromise, but I don't see you at all willing to do so.

Your need to be right, to have it "my way or the highway" seems to be the bigger issue here. Going into therapy basically telling a T you won't have things any way but your way isn't going to foster any willingness on their part to give you an inch because, I suspect, they feel you may be prone to stomp all over their boundaries. Thus, they feel the need to hold very firm boundaries with you to start with. You're creating the scenario where you are basically forcing these T's to hold even firmer boundaries as a defense against your black and white thinking about this whole issue.
