I take on board what you say. But it still doesn't really answer my main point: why keep up your "crusade," If I may call it that, after so long? Surely there is nothing new to say here.
But there might be new people to hear it. Even if there aren't, I enjoy the mental exercise of framing the arguments, identifying fallacies, spotting my own presumptions and assumptions at times.
On here, you are either talking to the converted (to your views), or to a small handful of theists, who by now, you must realise, are not going to be persuaded by you. Why not seek a wider audience, and perhaps make some headway, or at least find what may be a different set of arguments to contend with.
This isn't the only place I comment
It's a good place to practice, though.
May I say, that it is not much of an argument to sink to the level of the "fairy tales" approach. You should be prepared to discuss at a higher intellectual level, if you seriously hope to persuade people of your views.
Except that there isn't a 'higher intellectual level' to religion. There's a wealth of historical evidence for the in depth analysis and navel-gazing intensity of religious study, and nothing new has been produced from it. There's still no evidence for a god, still no defence against theodicy, still no rationale by which any of the religions make sense. That's not intellectual, that's academic - a genuine intellectual would review the history of Theology and say "Hang on, we haven't gone anywhere in hundreds of years... let's jack this in and do something useful".
People believe these tales of magic and mighty heroes, whereas they no longer believe, say, the Norse or Greek tales of magic and mighty heroes: that's not a validation of the Big Boy's Book of Jewish Bedtime Stories, it's an indictment of the people that pretend there's a qualitative rather than quantitative difference.
You say, effectively, that it's rude to accuse Christianity of believing in fairy tales, and that may well be the case, but being rude isn't necessarily being wrong. This is a debate, and wording is chosen for the impact it has, both on the opposition and on the audience: describing religious claims as unevidence, unsubstantiated, unprovable or untestable is all entirely true, but lacks a certain impact.
"Christianity is a fairy-tale, and Jesus is just a hippy wizard", that's a phrase that's going to stick in the mind.
