Is bad grammar immoral? In a minor sense, I'd say yes, because you are not communicating as effectively as you could. Bad communication wastes time, and time is life.
The same is true for profanity, if overused, or if used inappropriately. For instance, if you meet your future wife's parents for the first time and you start swearing profusely, the implication is that you don't really respect her family. Even if you really do respect them, undoing the confusion/damage will take some time. That's an immoral, unjust waste.
Vulgar language should be used appropriately: when upset (generally among people you know), or when with intimate friends as a means of implying: "you get me. I can swear around you and you'll know it's a sign of trust rather than disrespect." Swearing when speaking to strangers is like going shirtless on an uptown street: it's baring too much of yourself to people whom you aren't on intimate terms with. They don't deserve it; it's unjust.

Profanity certainly has its uses. Colorful or shocking language can be used for emphasis, for example.
However, using such a tool with abandon would obviously reduce its utility in providing emphasis because you've made it common, so that would be one reason for sparing, judicious use.
More significant is the observation of manners/politeness: if you wish to live around and work well with others, then being oblivious or indifferent to unnecessarily shocking them with vulgar, graphic language is counterproductive. Someone who demonstrates a lack of sensitivity to their social context is waving warning flags.
