New Mandalorians ARE the Canon Version of the True Mandalorians
Ok so, a long time coming but here's the gist:
I truly think that the New mandalorians are, to canon, what the True Mandalorians are to fanon.
Yes fanon, not Legends Canon because they aren't as good as people make them out to be in, you guess it, fanon.
To start, let's established what I mean with Fanon True Mandalorians and Canon New Mandalorians.
New Mandalorians are show to:
Want to move on from their Imperialistic History
Not erasing any history (see: murals in the city) nor the language (see: the mando'a all over the city, in the Academy and Satine openly speaking it) nor even their warrior traditions (see: kids still knowing how to fight)
Seem to be the majority of the population, composed by a big mile by Non-Warrior AKA the majority of the population even before the civil war.
Are hated by the Death Watch
Want and Do focus on the non-warrior traditions and elite (after centuries of it being the focus on their sector), but not to the extreme of banning all warriors (see: The Mandalorian guard, the Protectors - who are lead by Fenn Rau) instead possibly asking the Warriors who Refused to back down to not start shit in return of having the least damaged planet/moon aka Concordia
Are trying to make Mandalore and it's people Better
Those outside of the Royal Guard and the police don't seem to wear armour, though those seem to not be the bounty hunting version of it and those who Don't wear it certainly seem to use clothes with the beskar heart - the Kar'ta Beskar - in them
Follow a more progressive type of government - out from the Warrior's Elite control and more into the non-warrior population (aka the majority of the population)
Don't seem to have problems calling non-warriors Mandalorians as long as they meet a certain criteria
The Fanon True Mandalorians, meanwhile (from what I could gather from fanfictions):
Warrior Focused but out of necessity because of the Civil War, but don't seem to want to focus All on the warriors
Are Hated by the Death Watch
Don't seem interested in going imperialists
Are trying to make Mandalore and it's people Better
Wear Armour even outside of battle
Don't seem to be the majority of the population - fanon varies between them being a minority or being a big part of the population (or at least, the minority with the support of non-warriors)
Follow a more traditional Mandalorian Government
Don't seem to have problems calling non-warriors Mandalorians as long as they meet a certain criteria
From these, we can that they ARE similar, and if we go further into semi-canon (which is iffy but we are handling fanon while talking about canon, so I will allow it) we do know that the New Mandalorians and True Mandalorians were at least relatively neutral towards each other, imagine if the True Mandalorians were their fanon self? They would get along way better!
But that's not the point of this post, the point is to show how the New Mandalorians are the Canon Version of the True Mandalorians with a few tweaks - which I do think I already proved from the points alone.
Out of the 10 points I spoke about, 6 they immediately agree on (even if on the last points they need to have a conversation on what their mutual criteria would be), with the first and seventh point being an half point since they are in a civil war and seem to be part of warrior clans, and we were not shown any of the warrior clans in the New Mandalorians outside of Satine, a Pacifist that leads by example (hence not using her armour, especially because she might have trauma related to it), Korkie, a child that may very well not see the point to when everyone doesn't wear it + there is peace (maybe he only used it from traditional celebrations), and Almec, who doesn't wear the armour until there's a civil war again.
Either way, summed up it's 6 points out of 10 that they agree on, more than half.
The New Mandalorians could simply be the True Mandalorians but evolved post war, or, as I suggested in the start of the post, they ARE the Canon Version of the True Mandalorians.
Simply because they weren't wearing armour at all times or fighting or part of the War, people threw them under the bus as 'genocidal colonizers' (even though nothing in canon suggests otherwise, if anything it suggests the opposite).
Personal Thoughts: The Canon New Mandalorians and the Fanon True Mandalorians are a LOT more alike than people think and it's sad that all they can seem to write is 'New Mandalorians Bad, True Mandalorians the BEST EVER'.
