Between your two examples, the second one is by far more demeaning. Cursing is not always an example of being demeaning to another person. Your first example has two curses in it, to some just one, but they weren't directly aimed at the person being spoken to. That's just being rude by using language that many people may not like to hear in a public space. If your first example was an abrasive comment directed at the person, such as "You are a fucking idiot because you can't follow simple naming conventions that a slightly trained monkey could follow!", then it would be demeaning towards that person. I would also say that your second example isn't exactly polite either.
