Sam: My rebbeim are not poskim–they do not have personal opinions on this that I am particularly concerned for. I do follow them regarding which poskim they rely on in a machlokes, though.
I know absolutely nothing about the halachic aspects of this shaila. But I’m sure you can find the arguments in modern seforim, or by speaking in learning with a few poskim.
I’m a bit confused now, though. Are you saying now that you don’t know the reasons they say? Does that conflict with your taking such a strong stance on this as to think they are all in clear error?
