Coworkers who swear are just more memorable. Plenty of great ones quietly get the job done without a fuss and without seeking to always cause a scene.

Swore at or swore while talking to? There's quite a big difference. I don't see profanity as inherently abrasive, and some of the biggest dickheads I've met in workplaces didn't swear much at all (some were of the Professor Umbridge type, so kept up an air of perfect professionalism)
