I am with Toi on “frei”. I always thought that “arbeit macht frei” was written with a spark of true nevuah. The non-frum thought that they were frei when really only “arbeit [fur Gott] macht frei”.
I think of shiktaz the way HaKatan describes it. As a way of subconsciously brain-washing myself to the idea that their ways are lowly. I don’t use the other word.
I heard similar to WIY regarding tinok shenishba, that today its not so poshut for someone to be that. Still “ein HKB”H bo b’tyronia im biryosav”.
