I think in particular reference to the completely unfounded and unrealistic suggestion of resurrection being historically accurate and scientifically possible, the particularly weak religious and sociological defense absolutely disqualifies it from any serious consideration at all, yes. Someday we may have a conversation about, if there's any science or history at all on its side. As of now however, there's literally not a single reason to acknowledge its merit beyond superstition and fantasy.
Out of intellectual honesty, and for what it's worth, you're right - there really must be a differentiation between History and mythology. Empirical standards absolutely exist in History - otherwise, for e.g., we'd teach that King Arthur existed, had a 14th century military in the 6th century, had a round table, a huge castle, went looking for the holy grail, and so on.
I've said before that I question whether or not "Theology" is even really a valid academic subject. I'm sure there are quarters where I'd get into a great deal of trouble for suggesting that, but really, my only point is that we as a society and as educated people really bend over backwards to afford religion a nearly untouchable spot where [empirical] standards that are applied to quite literally
everything else are not applied to it. I only think that should change.
