Maybe. No idea. Even if people started to accept the swearing maybe the speakers knowledge that he has a special exception allowing him to say these words and it's okay would be enough. Or maybe he still considers it bad to swear even if other people thinks it's okay. It's not like brains always act in some predefined logical way.
I think it’s more to do with my ability to produce certain sounds that various swear words make easier. It’s not that I’ve any major hang up about swearing. The mental hang up is elsewhere, such as feeling anxious ordering food.
