You don't know it doseofreality but you've invoked a bad row of dominos. Ehrman's work is based on the incorrect model particularly promoted by Walter Bauer and that model has been soundly refuted by orthodox modern scholars meaning that your #2 link which states the opposite is patently untrue.
But then that same link asserts there is no actual consensus amongst scholars for the historicity of Jesus Christ and then makes great misrepresentations to "prove" it. An outright lie. The truth is that the vast majority of Phd biblical scholars both past and present, including even Bauer and Ehrman, support a historical Jesus. I don't know what that guy's smoking but it's not tobacco.
Now understand that Raphael Lataster bases his work on the same false model as Ehrman. Hence, the analogy to a bad row of dominos.
Read 'The Heresy of Orthodoxy: How Contemporary Culture's Fascination with Diversity Has Reshaped Our Understanding of Early Christianity' by Andreas J. Köstenberger (Author), Michael J. Kruger (Author), and Ian Howard Marshall (Foreword) as a starting point to see how modern scholarship has refuted Bauer's false model and subsequent false assertions with respect to Christianity.
So Bauer, Ehrman, and Lataster are all working off a false refuted model and adding to it their own assertions many of which are fallacious. One of many examples of this is how they construct conflicts behind variant readings and then posit this conflict as a historical absolute back onto the original. And, they are inconsistent in the use of criteria when they do so because they don't want to introduce evidence disproving themselves. Furthermore, the set of sources they invoke as earlier have not even been recognized by critics to be plausible as a whole. They use straw men, ignore that which refutes their false view, etc... I could go on and on and on and on.
The ignorant unbeliever then reads Bauer, Ehrman, and Lataster and feels justified in their unbelief when literally: it's the blind leading the blind who then repeat the misinformation in their blogs etc...
That last link in #5 is wrong. If you want to read a good introduction on Gospel dating, I recommend 'The Many Gospels of Jesus' by Philip Comfort & Jason Dreisbach and 'The Origin of the Bible' by F. F. Bruce, J. I. Packer, Philip Comfort, and Carl F. H. Henry.
