“Mesorah is an inauthentic concept. I hold like the score of rabbis I cited above.”
If we are to ascribe a lack of authenticity here, it would be to yourself. I doubt that the rabbis you cited would endorse the statement you made about mesorah. But you don’t care for their opinion on that do you? You only care to quote or follow the teachings that suit you, jumping from one authority to another whimsically, leniencies adding spring to your stride.
I’ve refrained from commenting on your attitude until now, but it’s enough. I’m not sure what you see in Judaism to begin with, but if your purpose here is going to be to thrust your 20-something year old sophomorism in our faces then I wish you would leave. A person with your background should be asking more, and questioning less. And never lecturing to others what you ill understand yourself.
