I'll just say for myself (and I know I speak for Kahlan as well), I have alchemy symbols of human transmutation (from Fullmetal Alchemist) tattooed on my forearms. I have them because they have personal meaning and application to me. I have never been and never will be the kind of person to get a tattoo just because it "looks cool". Everything has to have meaning, and these tattoos do. It is not just an homage to an anime I love, it is also a symbol of my faith (which is, obviously, not just a trend or phase). Basically, just as the symbols were used in alchemy to bring one back from "the other side"/death, so have I been brought back to life by Jesus Christ. So, for me, my tattoos will always have meaning. But, I don't speak for all, of course.
