Adl – there is an expectancy to understand the 7 mitzvos. The dor hamabul, sdom, etc…were held to task for not coming to them through sechel. That doesn’t mean that every intuition we have is valid and we need to “reexamine” torah as he held, mitzvos which don’t fit into current intuition of ethics and morals.
My point about mechias amalek is that Lichtenstein “grapples” with how a merciful G-d could command violence, because to him it’s unethical. For believing Jews, it’s not a question; Hashem is the one who creates ethics and who dictates what is right and wrong.
You haven’t addressed my main idea, that intuition is subjective, and constantly changes by time and place.
Christians believe that our moral feelings are determinate in and of themselves; they use this as a substitute for a religious legal system.
Lichtenstein may have earned a semicha, but bmakom chilul Hashem ain cholkin kavod larav, and every time you mention him it’s a possibility of causing a chilul Hashem…
