rationalfrummie,
there is a moshol – I think its in the Shaarei Teshiva L’Rabeinu Yona – if someone were to tell a king “I will listen to everything you ask of me and follow all your rules – except for one which makes no sense to me,” how will the king react? Will he consider him a loyal subject because he keeps 99% of the rules or will he throw him in jail for daring to suggest that he gets to decide which of the king’s rules make enough sense to be kept.
None of us are perfect but at least we strive for perfection and understand that what we dont do right is our own shortcoming. But when we make a movement which says 95% of the Torah should be kept but the rest is outdated…that is very far from torah judaism.
