Harry Potter vs Jesus

There is a common trend among internet atheists that, if you want to prove that Jesus didn't exist, all you have to do is show similarities between Jesus and some other mythical figure.  Of course, this approach doesn't work for two reasons.  First, it ignores the wealth of positive historical evidence we have for His existence.  Second, superficial similarities are irrelevant; the differences (of which there are many), are what's important.

Don't be fooled: these arguments are vacuous.
