This is a good point. There's no way of knowing simply from the phrase "Crucified Christ" whether the speaker means it as a joke or as some sort of actual statement of religious belief.
Mormons actually regard the crucifix itself as offensive. They argue that using it as a religious symbol is tantamount to worshipping the weapon used to murder Christ. Obviously, most traditional Christian religions don't share this attitude, but it has a certain logic to it.
I remember taking a Japanese Buddhist on a visit to a Catholic church once. She walked around the chapel, looking at the depictions of the stations of the cross, with Jesus dragging the crucifix and being tortured with his crown of thorns and blood dripping down his forehead. I don't know if she was "offended," exactly, but she certainly found it scary.
