No he didn't...

No threats were being exchanged until 0:43, and the first one came from Garrosh...
Also, this was not their first encounter, their first interaction was before the shattering, when Thrall held a meeting, Garrosh was still a general at that time, not a faction leader. It was at the point that Vol'jin said that the people were happy with "our (the Horde's) success in Northrend" that Garrosh opened his presumptuous mouth and insulted Vol'jin with: ""Our" success? Troll, you played no part in the Horde's victories in Northrend. While I led our warriors against the Lich King, you merely took back a few scattered islands."
That was their first interaction, and it started with Garrosh ignoring the fact that Vol'jin retaking the islands happened
after the fact, and that his Darkspears had been contributing to the war effort against the Lich king same as anyone else, and being a massive hypocrite considering Thrall had by and large done just as little
in person on the continent of Northrend as Vol'jin had. Thrall and VJ, with the exception of the former joining in during one small scuffle outside of Warsong Hold, being a spectator during the tournament and saying a few words in Dalaran, did the exact same job: they led their people from the capital and sent forces to Northrend... but he's only belittling
one of them, for doing their designated job as
leaders?
For someone to demonstrate such a staggering ignorance towards one of the many races he was supposed to be left in charge of, I would've been more than a little concerned as well...
All we know is that Vol'jin tried doing something he was charged with doing; advising the Warchief, which said Warchief promptly dismissed as "talking back" at him. Yes, he lost his head and said some nasty words (that he
for the most part since then negated by supporting the Horde's campaigns during Cataclysm and answering the Warchief's calls to battle) but the one that instigated antagonism was Garry... Not Vol'jin...
Mostly because most of the people in here show the same level of ignorance regarding the Darkspear that "Garry" did, both in terms of what they've contributed to the Horde overall and the reasons why Zalazane's reign could last as long as it did... I acknowledge a few certain out of character moments that reflect piss-poorly on the character (troops charging at the juggernaut, his diplomatic snafu during 5.3), the problem is that most of you only acknowledge these things and
nothing else... because that's what's most convenient for your position...
It's not a coincidence that the effort to bring Zalazane down happened during the first lull between world-threatening incidents that the factions got to experience since pre-WoW's timeline... As Ramz has already tried to point out; Zalazane claimed the
majority of the tribe under his spell, which
at best left Vol'jin with 40% of his tribe, and at that point you can't afford to dilute your forces any further... So he made a choice, and that choice was to aid the Horde during its campaigns throughout WoW by focusing his forces there. Garrosh's prejuidice against the Darkspears stemmed from his total lack of understanding of why these islands weren't reclaimed sooner...
Says the one on the side of the argument which has to remain ignorant, willfully or not, to parts of the lore pointing to his and his tribe's merits that contradicts their bias... I don't care if people dislike them out of preference or how underutilized they are, I
do care when people are being intellectually dishonest just to maintain their narrative...
