That one is easy to answer. Everyone loves the Jesus Game. It doesn't matter how a person plays it, but there is one overriding rule: Never Kill Off Jesus.
That was done over 100 years ago and many times since. By the 1930s, however, every theory of Christian origins with a Christ myth had been answered. Sure, there have been more mythicists since, but they were answered already and answered again both by citing the previous answers and reframing them in the new.
So your "Jesus game" exists only in your imagination. You cannot know what has been argued long before you were ever born through observation, and thus your conclusions about this game are incredibly limited. When Schweitzer addressed basically every mythicist argument there was and is you were not a thought, much less born. Perhaps you were born when the non-biblical historian Grant went through the various arguments against using the gospels as evidence and showed how thoroughly biased and baseless these were (given the nature of ancient historiography and religion), perhaps you were not, but if you were born you weren't even an adult.
And that's the one of the major flaws of your "I observe the human heart" position. Like all humans, you and I are tiny little blips of insignificance. It is the recorded history, anthropology, and archaeology that allows anyone to say anything about humanity as it has existed for the 100,000+ years it has. Not observations of your Christian family.
So you observe modern Western biases like your family of Christians (and through them), and those of us interested in the past read what you can't even read because you can't understand the languages. You are limited to your subjective experiences tainted by your biased Christian upbringing which you apply to Christian origins; just like those antiquated biased scholars of old who projected their Western upbringing to religious movements of past centuries (those who, like you, called these "primitive times").
I don't project elitism into the past. I study it. Those whom you mock do so too, but as you have not read them you would not know. You are left with your biases. And if that makes you satisfied, then I envy you for being satisfied by ignorance. I would gladly trade all the access to sources, all the languages I know, all the effort and time I've put into studying, for assurance. But I cannot. I cannot bring myself to tolerate fallacies. You can (even if via denial).
Because then the game is over.
Were that true, it would have been over before you existed.
I think it's why, as a group, Jesus historicists tend to argue with such intense emotion, while mythicists seem more laid back.
I thought you claimed not to know who the mythicists were or what they were. Would you like me to quote how much they insult, marginalize, ridicule, mock, and otherwise use emotions and passions to address those whose knowledge far outstrips their own? I can. Richard Carrier has a degree in ancient history. His dissertation was on Greco-Roman science. He hasn't published a single accepted piece of scholarship in his field. Do you know the one field which accepted a paper of his as scholarship? Historical Jesus studies. Not his field, but the biblical scholars.
Just my personal view of it, of course.
What other view do any of us have?
