И, Yazeed, при детях и девушках (женщинах) воспитанные люди не матерятся никогда. А если всё-таки не сдержались или не заметили, что рядом не только мужчины, то говорят: "Извините".
Man is it just me or does it feel like its 1929 in up in here?

The only Russians speakers I ever met who didn't swear were fresh off the boat orthodox immigrants from remote regions in Donetsk and Crimea who were so extreme they didn't even dance, or drink, let alone swear.

I've never met a Russian who didn't swear, at least sometimes. Even the super orthodox ones would joke about it sometimes, saying things like "пошёл на х...улицу! Гы Гы Гы!"

Everyone is making it sound like if you say bad words in Russian you are statistically more likely to beat your wife, becomes an alcoholic, and traffic drugs between different countries who's names end in some arrangement of "stan".

Swearing may have a time and place (songs included whether you like it or not) saying that people who use bad words are not at all воспитанный is a little extreme... Crazy extreme.
