Alot of their publications will quote from various sources and you think wow they've really done their homework. I know I made the mistake of not looking up the info myself and checking their sources. Of course their sources tend to be biased because they are trying to prove their point. You may find one source that says they think Jesus died on a stake and they will quote that one source, even taking it out of context to prove their point whereas you will find 10 that don't back up their line of thought. My mistake and the mistake of others (perhaps) is that we don't do our own research, we take their word for it and they suck us in.
