Luke 23:34 “Father, forgive them, for they do not know what they do"

Somewhat controversial but relevant.

Personally I feel that ignorance is not a factor that should absolve someone of their actions, it should however mitigate things. What is probably more important when judging a person on their actions is their intent, a person might use such conditioned behaviours because they have served them well and become habit, the question is whether there is malicious intent or not.

That at least is the way law looks at things.

I prefer the route of showing them where a trait I dislike comes from and why they've become conditioned into doing it. Some people will vehemently deny it and others will be a little more open minded. When a person agrees with where it comes from you can also call them out on it in future and never have to deal with it again. Generally in a fun and playful way of course.
