I think you misunderstood my point. I am not saying that the "Jesus myth" is in any way real under any argument.
I am saying that the idea that there was some guy similar to David Koresh upon whose memory all the myths were piled is simpler than believing that there was no actual person and that some people simply decided to make him up. Obviously, almost all the stuff they said about him was made up.
Just about the only parts that are true are probably the parts they try to so hard to fit into the Messiah prophecies. He was actually born in Nazareth, but because the Messiah was supposed to be born in Bethlehem his followers in later years had to make up a cockamamie story about a census, accidentally getting the dates wrong and overlooking the fact that such a huge undertaking would probably have been noted in Roman records, etc., etc.
I understood what you were saying just fine. It's a good argument and one that I've made in just about every post I've made in this topic (and that's quite a lot). The parts where we can see the gosel writers struggling to explaining something awkward (and usually failing rather miserably) are precisely the things we have good reason to believe have a historical basis.
Now that said, I think you are engaging in a little bit of rhetorical exagerration saying that almost all the stuff they said about him was made up. There are lots of little things that they have no reason to make up but are still well attested, meaning we can be pretty certain they did occur. The father of Joseph being a carpenter, for instance, or Jesus having siblings, or him being betrayed, or him being an apocalyptic preacher etcetera...
But as I said, I agreed with most of your post. I only took issue with the parts in the blog post you linked to that I think were false. The alleged (but overblown) simillarities with Krishna etcetera being one, and the inaccuracy concerning the references to Jesus in ancient historians being another.
