Seemingly contradictory? It also lays OT vs OT and NT vs. NT and the same issues occur. You can try to rationalize away the internal contradictions, but it doesn't make them go away.
Well Tawnos, ol' buddy, I really don't know what to tell you. I'm absolutely sure that the website can take OT vs OT and NT vs NT just the same as it did with OT vs OT, and again the only thing I can tell you is that the context of passages is SO important to what they mean. Taking a single passage from one place, and comparing it to a single passage in another where the topics are completely different makes it very easy to give the impression of contradictory instructions. Again, if you read from beginning to end you get the full scope of what is happening and what is being discussed.
If you're really interested, start looking at some of those contradictory passages, pull out the Bible, and then read the entire chapter instead of just looking at those single verses. It takes a lot of reading, but eventually (in my experience) those things that look a certain way when pulled out of context suddenly make a lot more sense when plugged into the bigger picture of what is happening. The overall message remains pretty static all the way through, although some nuances do occur.
And yes, there are some facts that are contradictory in the Bible. As stated, anytime humans get introduced into the picture things get mucked up. Here's three freebees for you.
-The names of the original 12 apostles change depending on which book you read (Luke, John, Mat, Mark, etc)
-Many of the stories appear more than once in the Bible, with Apostles giving slightly different accounts of what was said (although the end message is always the same)
-In the Old Testament, Goliath's size in the modern Bible is several inches taller than it is in the oldest known written version of the story. (He's still a giant, but is basically larger than a modern day basketball player, not a Jack in the Beanstalk type creature)
I've spent a lot of time sorting through the 'contradictions' in the Bible, and have spent hours reading over histories of the ancient world, and probing articles on the subject. I still find things that are new, or interesting or exciting.
If you really want to explore the system of Christian beliefs then grab a book and go for it.
As for the difference between Christianity and the Westboro Baptist Church, I think I've already answered that, and the answer is still the same. Westboro preaches God's hate, while most Christian faiths are based upon God's love and salvation.
