The concept of foul language is, in itself, a superstition. The idea that a certain collaberation of phonetic sounds can form a word that is acceptable to society while another very similar collaberation of very similar sounds forms a word that makes baby Jesus cry is laughable and absurd. Take as an example, the words "buck" and "fuck". Both words consist phonetically of a "consonant-schwa-k" pattern.
Ironically, the only way to take power away from these "forbidden words" is to use them as loudly, proudly, and frequently as possible. Through a process called semantic satiation, a word that is used very frequently eventually stops sounding like a word at all, much less a specific sound that induces cringes and disapproval.
