> Are you seriously taking the position that Jesus didn't exist as a historical figure?
No. Just the position that the evidence for his existence is extremely thin, and nowhere near as strong as for Khan. Plus, the reports of Ghengis describe Just A Guy. The reports for Jesus describe Magical Super Powers. It is never unwise to be highly skeptical of reports of Magical Super Powers.
Skepticism, sure.
Unfortunately a lot of people do a lot of outright dismissing and call it "skepticism" for the sake of sounding high-minded and lofty.
