Sam2,
If? We see that it doesn’t. There are so few instances of HSV. If there were serious risks there would have to be more cases.
Remember, we are not talking about when the mohel has an active case. They already abstain then. As they do when they have sniffles or any active health concerns. You are talking if it might be transmitted when the mohel is solely a carrier. 80% + are carriers and there have been no correlation at all to any incidence that can match that.
You may as well ask if there would be the same reaction to R Tendler if he were chasidish. From either group. It’s an inane question.
