i believe swear words are pointless. swearing either means a lack of better vocabulary or a cheap excuse to look angry, badass, emotional, or "mature", when really it is immature (or both).
think about it. most people swear out of anger, therefore implying thoughtlessness and rashness, or out of a desire to look more "mature" then others.
there are exceptions for swearing, i believe, in poetry and literature, as to make a point or describe a feeling, but seeing as no one here writes their posts as poetry, i really see no cause for swearing.
