Let me rephrase...Are there any christians out there that have actually studied other religions.?

or is christianity the only one you know anything about. I've learned when I live in the south, we complain about the people in the north. when I live in the north, we complain about the people in the south. I'm looking for answers from people who have studied more than 1 religion so they can say they've made an informed decision instead of a bias one.
