This doesn't appear to consider the implications this has for other religions; namely, if the story of the resurrection is true, that means that all (or most) other religions must be wrong.

This is still a much weaker counterpoint that the impropriety of multiplying probabilities, unfounded assumptions of honesty, and (not mentioned) the problem of survivorship bias: there were likely hundreds of such accounts during that era, but only one of them happened to evolve into a religion and have its writings and accounts preserved long enough for us to see them today.

Have at it.
