Well, you can certainly cherry-pick a reasonable and nice Jesus. The problem is, yes, that the guy is horribly inconsistent and even hypocritical, if you don't exclude SOME stuff attributed to him.
E.g., you have the guy preaching non-violence on the mount, but in John 2:15 he actually puts in the time and effort to make a nasty weapon, a scourge (really, it's the same word as for the one used on him at the end), to clear the temple of merchants with. In the synoptics, Jesus just loses it on the spot and starts shooing people, but in John he first goes and makes a weapon, i.e., it's a premeditated armed attack. Not quite so nice Jesus now.
Plus, if he did clear the temple, that's some tens of acres and some hundreds of merchants and probably like a dozen armed guards who were there just to prevent this kind of thing from happening. No matter how strong his Kung Fu was, it would take an armed attack to clear that place of merchants. So, you know, an armed attack on a government institution, hmm, that doesn't quite sound like he's practicing what he was preaching just a couple of days before. In today's terms, it's like if some guy went to Washington DC and did an armed assault on the IRS headquarters. Not only it wouldn't pass for a nice guy, but I think even most Teabaggers would distance from him as fast as they can.
E.g., he tells people not to judge, yet he feels entitled to rant at length against the Pharisees and call them pretty nasty words, like "sons of vipers." In John 8:42 he flat out calls the Jews (John doesn't make distinctions like "the Pharisees", for him it's always "the Jews" that are the evil guys) "children of the devil" for not just believing Jesus that he's the messiah. Heck, in the same sermon on the mount where he tells people to not judge, he compares people to dogs and swine if they don't believe his stuff. Which would be an insult even nowadays, but back then in Judaism swine were fundamentally unclean animals that even God told people to stay away from, so, you know, it's a pretty nasty judgment to pass.
E.g., he's usually cherrypicked as some progressive guy who established that doing away with most of the OT stuff, like Christians very soon did. And really, clearing the temple of, erm, people who were doing things in accordance to what God said that temple should be for, would kinda point that way. But then he has a nasty out-burst against the Pharisees for not stoning children who give lip to their parents any more. It's a "wait, WHAT?" moment, at least for me. You have him suddenly arguing the exact opposite, when it helps him do a tu quoque.
E.g., he's supposedly a peacenick hippy, but a possible non-miraculous reading of John 9:6-7 is that Jesus and his buddies find a beggar pretending to be blind near the temple (he supposedly can see afterwards, so if you don't believe in miracles, he was probably just one of those fake disabled beggars), rub mud in his eyes (presumably by force, because I don't imagine any guy blind or not would just let you rub mud in his eyes, not the least because it would scratch and hurt like heck) and send him to wash his eyes in a pool that was at the frikken other end of town and down some stairs. Sounds more like what an annoyed psychopath would do, than a gentle and caring hippy Jesus.
Etc.
Plus, it doesn't help that Jesus reads as a complete
Black Hole Sue. He's always in the centre of attention, things always go exactly how the Black Hole Sue planned them, people always deliver the lines that just set Jesus up to say his line, they always fold no matter how much that line would suck IRL. (E.g., as I keep saying, when the objection to Roman coins and taxes was precisely that putting the emperor's head on them makes it idolatry, saying basically, "it's ok because, see, it has the Emperor's face on it" would be exactly the wrong thing to say to that crowd.)
So, really, you have to tone him down a bit there, before he starts being an even remotely plausible real person.
Mind you, it's not flat out impossible that Jesus was a hypocritical politician type, who argued both sides of an argument even in the same speech. But it's not quite the kind of Jesus most people want to cherrypick.
