No, it isn't, Lighter. ;-) It's quite easy to think about.

Look, there are a vast number of people in the world who have a high opinion of Jesus and his teachings...some of them Christians...some of them belonging to many other religious traditions...and some of them belonging to no specific religion at all.....who do NOT take the Bible as an inerrant source, and who are well aware that the various books of the Bible came from a great many different writers who were also not an inerrant source. Duh!!! Is this hard to figure out, knowing the general state of humanity in any era, past or present?

Your argument, however, appears to be directed at people who DO think the Bible is an inerrant source. Well, where are they? Are there any here? I don't think many of them are on this forum. If there are, then they're probably avoiding responding to you. Perhaps you should go where these people ARE and battle it out with them...or are you just having some fun here kicking around a favorite customary punching bag of yours because it feels so good to do it?
