I understand your point, but at the same time we cannot have forums for every nuance. I think most folks understand that. Every one of us has to slightly change our behavior in order to be a good member of society (or even this forum), so you should look at the glass as being 1/2 full and say “Hey, if the homeowner wants me to take my shoes off in the house, I will do it”......When in Rome.....
Also, you must consider the “mass” viewpoint - meaning if your grand dad put a stove pipe out the window it may have been fine for two reasons:
1. You didn’t hear about the guy 50 miles away who did that and burnt the house down
2. Grand dad had common sense
I would argue that there are some things we know more about today, and that in terms of actual recommendations we should take the conservative end.
