Sam and DaMoshe, IIRC, Hakatan keeps the terminology hashkafic, not personal. You’ll have to link to an occasion in which he did otherwise.
And if you think a hashkafic disagreement is personal, then DaMoshe is guilty of this when he talks about Satmar.
If I had time, I would link to numerous times when Hakatan has clearly stated that it’s not personal. Plus, bimchilas k’vodo, DaMoshe’s rhetoric was far more personal, directed at a specific individual.
