I'm sorry, but I don't see how either of your two points are demonstrably "historical facts." But even if they were, neither proves that Jesus was an historical person. Just because someone uses a person or identity for their own agenda does not make that person real. You'll have to make a stronger case for your assertion and show why you believe that it follows Jesus was real just because his name was invoked for political reasons.
Richard Carrier & Robert Price make very good scholarly cases that Jesus was probably not an historical character. The weight of evidence seems (to me at least) to favour the mythicist position.
