That is not my position. That is Rav moshe Sorotzkin with him quoting rav Dessler.
Again.
Being too critical of those whom you felt were lax about safety measures, [He is specifically referring to COVID] Relying too much on protective measures [he is still specifically talking about COVID], are examples of kochi votzem yadi – thinking the result is from the strength of your hand -.
This characteristic is the main characteristic of the eruv rav. These behaviors of yours (and yserbius) are emulating the eruv rav.
Not my words, rav sorotzkin and rav dessler.
“the difference here is a highly transmittable disease.”
No. He was specifically referring to COVID.
