Reply To: What did people do before Rashi invented Rashi tefillin?

DaasYochid: The question is:how can you have a machlokes altogether? Open your father’s tefillin and look! It is not relevant how Rabbeinu Tam may have learned the sugya.. Rabbeinu tam inherited tefillin from his parents and grandparents- how could he reject those? Does this mean that. according to rabbeinu Tam,everyone before him did not put on the right tefillin??? If this would happen today with any other matter of halacha, they would be ostracized and drummed out.I cannot imagine anyone questioning a set halacha and getting away with it.
