On a more serious note... As ridiculous as the lightsaber is in essence due to being nigh unusable for actual combat by anyone who doesn't use the force or who doesn't have the appropriate cybernetic enhancements, I'm not surprised that people in general accept it as its designed in a fashion that makes it look like it could work as a sword.
(this overly long post isn't really refuting anything you say, btw, it's mostly using it to comment more broadly) The trouble with all this is, is that when you start to nitpick the weapon the entire concept completely falls to pieces.
You say most assume it could look like it functions as a sword. But what
kind of sword? Single blade lightsabers usually have a grip for two hands, and are used as a primary weapon. So is it a longsword/hand-and-a-half sword? Those tended to have - ahem... - crossguards of some kind. As the vanilla design doesn't have a crossguard, what kind of sword is it supposed to function like? Because swords are just tools to do a specific thing - they have a function, and their form serves that well or poorly. If a new function/requirement arises, then the weapon evolves to cope, becoming both better and, usually, worse in different ways (all weapon evolution is a matter of compromise and context).
If it doesn't have a crossguard, might it perhaps be used mostly with a shield? That'd make sense, but in no films do we see any Jedi or Sith wandering around with a shield.
When you start to compare what kind of swords a lightsaber might be an analogue for, you come up entirely empty handed - there can be no comparison, no analogue. I'd say that renders
any nitpick based on function useless. From what I know, swords used historically by themselves as primary [battlefield] weapons were rare; you were either often in armour if it's a European longsword (crossguards generally evolved to compensate for a lack of a shield), or you were in a specialised and seemingly very rare unit of greatswords (
possibly to counter pike formations). I'm aware the Chinese had whacking great battlefield two-handers which seem to have been used against cavalry. A longsword type weapon was a side-arm, and usually little more than that. So already the Jedi and Sith are breaking the most fundamental of martial fundamentals by pitching battles and duels with what amount to back-up weapons (re length and reach).
...'cept they're also Force users, which is their true distinguishing feature.
The rule of cool obviously is also a big factor.
I'd say for a
sci-fi laser sword used by space wizards that can never be compared to a real life counterpart, the rule of cool's the only thing that matters.
Nor are they capable of protecting against enemy sabers like actual swordhilts were since any lightsaber will slice right through it.
But, again, we're comparing fencing techniques to lightsabers, which seems a tad pointless. The techniques of a weapon that cannot exist - and which would handle differently to a real, fully weighted counterpart - are entirely down to the discretion of the fight choreographers and director/writer.
And then there's the small matter that - if the blades are supposed to be weightless ('gyroscopic effects' aside, unless those numbers can be run relative to the hypothetical properties of a saber) - then the films themselves do an awful job of portraying how they'd handle, given all kinds of moves and flourishes would require use of momentum. On set the props had weight [https://youtu.be/rk1qghsNiok?t=2m12s], ergo those moves were possible. If a lighsaber was real, barely any of the techniques shown in the films would be possible, or they'd just be entirely impractical and unnecessary.
Going with the Sith angle, the design looks like something a Sith made as a prototype only to discard it for whatever reason later on given how unstable it looked. Or he got his hands chopped off by it and went back to a regular lightsaber after getting new hands.
Isn't Darth Maul's saber even more dangerous than Kylo Ren's? I'd say absolutely so. And, again, if the sabers are supposed to be weightless, much of Ray Park's technique would need to be changed.
If Maul can train to adapt to multi-universe defying physics (i.e. it doesn't handle like a 'real' saber in-'verse, and it can't even exist in our world) and cope with that double-bladed lightsaber, then can't Kylo Ren more easily adapt to a style that doesn't lop his own wrists off? All he needs to do is drop his grip a little, and adjust his style. We've not seen him fight, yet, only ignite his saber and take a big overhead swing. Perhaps he has a very distinct style which suits his chosen, obscure weapon? Hell, he might even use it for just a few scenes, we don't know.

Everyone knows how a lightsaber functions though
Really? Because as I pointed out above, the sabers in the films don't cohere to lore that dictates they're weightless, so it seems George Lucas didn't even know how they "function". The truth is that the logic defying weapons have always been entirely defined - in design and use - by writers and directors. That was the case with A New Hope, Phantom Menace, and it's the same with The Force Awakens.
As such even a casual observer can look at the lightsaber's crossguard as-designed and say "Wouldn't another saber just slice right through those emitters?"
Quite simply: it's because the lightsaber is closer to being pure fiction/fantasy than a DA:I sword that it draws attention to itself.
I'm not sure my mind can't process that cognitive dissonance/double-think...
Realistic thing: needn't be realistic.
Fantasy thing: should be realistic.
With that broken/zen logic I really can't say come back with anything.
...gah, can't believe I've been sucked into this 'topic' again, and on a simple fluff piece about TFA, to boot.
