Is referring to a person or persons as "motherf*****s" ever done in a positive way?

@GlitterBug the context is what's bothering me. My adult stepson was outside and yelled loudly towards the house "Those motherf*****s over there...." (this is farm country and it was slaughtering day) in reference to our neighbors who possibly heard him quite easily. We are knew to the area.

Yeah...pretty sure he's wrong there. Even if he meant it well being new to the area means thats not appropriate

@GlitterBug I told him that's what they raise those cows for and his brother quickly says to me that its not like he (his brother) said anything wrong. I got upset and went inside.

I think they're both in the wrong tbh. I'd have been pretty annoyed at that too. @morrgin
