I'm with you. Heck and darn are fine, f-anything is not. I have suggested to my daughters that they may use more inventive words as substitutes. Just today I heard (screamed at the top of my 8-year old's lungs to her sister), "You are such a CUPCAKE! Get your petunia out of my room!" (Of course then little sister shouted, "Mommmmmmy! She called me a cupcake!") Uggggh.
