Joseph-
Really? That’s the best you can come up with? Kosher?
Well, let’s see…
Kosher must be kept EXCEPT under the most dire of circumstances i.e. pikuach nefesh.
Kibbud av v’eim must be kept EXCEPT for fairly common circumstances i.e. married woman’s priority to her husband.
So the statement “You must keep kosher” makes sense as a standalone statement because the exceptions are pretty rare. (As would “you must keep shabbos” or “you may not eat chametz” – also with rare exception)
Whereas “you must honor your parents” has fairly common exceptions so the statement as a standalone is more glaringly misleading.
Talk about inane contentions…
