Read “is OK to …” to mean a cultural norm, not a judgement made by my or yours real values.
My argument is then: It’s presently OK (in their culture); therefore (all else being equal) it’s likely to have been OK in the recent past, and is not a recent innovation; therefore it matches the definition for being a part of their culture.
The last link to “therefore it’s OK” that you propose is simply not necessary, I have already reached my conclusion.
Now if you read “it’s OK” as meaning I, User:DanArmak, think it’s OK for wizards to kill kittens, that would be a circular argument, and also a wrong one (because I don’t think so). But that’s not what I was saying.
