Because if the majority of people following a particular religion reject a prior view as false or wrong, then arguably that view is no longer part of the religion.
Religions aren’t crisp, unchanging, monolithic entities where everybody believes the same thing forever. If we’re talking about judaism in the sense of the views and practices jewish people actually subscribe to, then that seems like we are referring to beliefs they actually hold in a mainstream/current sense, not beliefs they previous held but now reject?
No, that is not what I said.
I definitely answered this in my original comment.
