My experience and advice are not much different than the others here.
I have never had much opposition shown to my interest in tarot, except from a couple people. Those were mild, and one went from "How do you believe in tarot if you're a Christian?" to "You'll have to teach me more about this." ;-) (I'm a 27yo male in a small town, and started tarot in college)
Saint Paul said "I have become all things to all people, in order that, one way or another, I may rescue some of them. But I do it all for the sake of the gospel, so that I may share its blessings with others."
I adopt much the same attitude with tarot!
When I'm with my pagany friends, and they want readings, we light incense, do the LBRP, and then do the reading.
When I'm with coworkers who are interested, I ham it up a bit, put my turban on, call myself Madam Zelda, then say, "I'm not psychic, you know. I'll tell you what the cards seem to mean to me. Feel free to interject if what I say seems to be refering to something else."
With complete skeptics, I say, "They're just cardboard pictures. It's like a Rorschach test. It's just a means to bring to the conscious mind what you already know.", and when "reading" for them, it's more me asking questions to provoke them to see their own answers in the cards.
For myself, that last approach is my own *concious attitude.* I *don't* think I have much psychic ability. However, when reading for myself, I go for the more "pagany" approach, since just as the cards can show us what's inside, what we *arange* outside can *affect* our inside. When I make it a holy endeavor, it *is* holy; when I make it light-hearted, it's that.
