Two of my characters had a large in game argument.

Kitsune sorcerer insulted my Wayang bard a couple times, after the Wayang was called an IT and compared to a goblin, this started a fight between them, she needed more respect while his character didn't see that as being disrespectful. OOC they are fine but it took up a huge chunk of time for the session, so at what point should I step in and how can I push them forward without just saying stfu and continue?

Two of my players' characters had a large in game argument.

My Kitsune sorcerer insulted my Wayang bard a couple times. After the Wayang was called an “it” and compared to a goblin, this started a fight between them: she needed more respect, while his character didn't see that as being disrespectful.

Out-of-character the players are fine, but it took up a huge chunk of time in the session. At what point should I step in? How can I push them forward without just saying STFU and continue?
