I disagree that use of profanity makes one uneducated and unskilled. There are many words we use everyday, the same words over and over, that aren't curse words, but that doesn't mean a person is uneducated for using them. There are many famous people who are known for being highly skilled and educated who used swear words.

As far as "The C Word" goes, I am generally offended by it, not so much for what it means, but the inequality of that word and words for men. While you said guys are using it, it's generally a descriptive of a woman, but there are no words that really sound as vile in describing an unpopular man as some words, including The C Word, that describe an unpopular woman.
