MDG -“Besides which, although I don’t know that much, I don’t think that the principle of “Ain Sofek Yotzay Meday Vaday” applies to attitudes/hashkafa.”
And why NOT? You don’t change things unless you know they will be better. That’s why we didn’t ask Hashem to get rid of Achashveyrosh because we didn’t know if the next king would be better! (This just illustrates the point, not necessarily about attitudes/hashkafa.)
