Please, Ukrainians, get rid of this word and start using "gospodin" or something like that.
There was time when Poles used gospodzin as well. But Russians and Serbs didn't make any claims to Poles regarding this. Everithing is changing.
Polish knights chanted Bogurodzica prior to their engagement at the Battle of Grunwald:
"Bogurodzica dziewica, Bogiem sławiena Maryja!
U twego syna Gospodzina Matko zwolena, Maryja"

Moreover Ukrainians use expression "szanownie panstwo" - a respectful community.
