“There’s a big difference between accepting a ‘rationalist’ explanation as Torah vs insisting that everything must fit in accordance with a rationalist ideology or else it is to be dismissed.”
So you can choose whether or not to accept the Ralbag’s rationalist explanations as Torah. But why do you think the Ralbag offered rationalist explanations if not because of a rationalist ideology? Granted there will be some times where he will accept things even when they are irrationalist but so will the people who were being attacked in the beginning of the thread (I think the only one mentioned by name was R’ Slifkin).
