Always_Ask_Questions,
Thank you for sharing those sources. They seem to fall into two distinct categories:
1. It is forbidden to call one’s parents by their names.
2. How to handle disagreeing with your parents
AviraDeArah’s hypothetical child certainly didn’t violate #1. Did he violate anything in #2? He didn’t disagree with any position held by his father, nor did he affirm his father’s words. In fact, the hypothetical father stated no opinions whatsoever, nor did the child. He simply asked a question: did you ever get that garment checked? It says wool on the label. The source you brought that has the closest relevance to AviraDeArah’s example was the Prisha: “But if there is definite proof that a mistake was made in religious matters, then one is obligated to point this out.” Not getting a wool garment checked for shatnez is a mistake in halacha which led to a clear and definite violation of halacha in AviraDeArah’s hypothetical. Perhaps you can say the son was not sure, but the son did not disagree or level an accusation against the father, or “correct him” as you wrote – he asked a question! Did you get this garment checked?
You leveled some serious charges against AviraDeArah due to his example which by even your own sources doesn’t appear to violate any clear issur in kibud av, and then implied that I look for excuses to get out of observing mitzvos bein adam l’chaveiro when I defended AviraDeArah from what I thought was unwarranted and harsh criticism. I think it’s possible you’re reading way more into the example than was actually there.
