Thinker:
You wrote, ” I do admit that whilst some of it (evolution and our ‘likeliness to other species’ etc) is apikorsus…”
I must correct you. This line is common. It repeated often enough that it gets its credibility from its frequency, not from fact.
Evolution is not kefira. (No, I’m not a student of Slifkin.) It is pseudo-science that is ridiculous. I would not apply the dignity of kefira to evolution. That would imply that it is a sound theory with factual basis, which it is not.
“Likeness to other species” is certainly not kefira, and the Gemora is replete with the drawing of similarities. Shlomo Hamelech tells us to learn certain midos from various animal species. The Gemora also describes three ways in which humans resemble angels and three ways in which humans resemble animals. The works of Mussar and Chassidus address the concept of “nefesh habehamis”, a reference to the “animal soul” that is part of human composition. This label of kefira is being used almost randomly, and this is not appropriate.
You are correct in noting that therapy is grossly misunderstood, and thus not appropriately recognized. The stigma is misapplied and injurious.
