Sam2 – whilst loath to defend Joseph, surely you appreciate that various different people have different approaches. One of these differences is whether a person looks to try and keep Shulchan Oruch purely based on “Vos shteit” or alternatively they want to go beyond the letter of the law. I must stress that I actually find both options to be valid and to have extremely logical reasons for them.
My personal preference is to work with what I have. When I work in Goyish palces, I use first names. Yiddishe places, Mrs etc. Of course its all fake because we’re creating false fences but we value that. Of coruse, that’s my personal preference.
