Not only is Mak'gora not a practice of the Tauren themselves, but those Tauren went with the option of aiding the Horde in its war campaign in order to liberate the Barrens even without Baine's help. There is no indication whatsoever they wanted Baine gone and they still achieved their goals from within the Horde. Now compare that to Baine. There is plenty of indication that he wanted Sylvanas gone. It's just that he didn't do shit about it within the Horde, he simply ran to Alliance like a lapdog and instantly bent over for Anduin. So congrats, your comparison falls flat on its face.
But I really do like how in every single post you've made in this thread your defense of Baine relies on throwing (or at least trying to, as in this case) someone else under the bus. It's almost as if you were inadvertently admitting that Baine's case can't stand on its own and for him to be not shit someone else must be at the very least guilty of the same thing as him.
You mean the Earth Mother that blesses Horde soldiers in one of the BfA quests? And since when does Azeroth operate on some kind of weird dichotomy when one has to act for the Alliance when they consider the Horde to be wrong? And why is that Baine didn't do shit about things like Blighted Tauren or Saurfang being "left to die" (in his deluded mind at least, because in reality Saurfang disobeyed the order to retreat right in front of Baine) and only started to give a damn when the family of his human friend was put in jeopardy? For someone that supposedly cared about the Earth Mother so much, he should have acted much earlier.
You mean the empowered no one on Azeroth aside from her confidants like Nathanos didn't know about until she blasted Saurfang's ass?
The system in which the only way to remove a leader one does not like is through combat is most certainly working as intended if that leader is capable of winning any challenge. It's a rather idiotic system, but those are two different things. No one forced the Tauren to join an organization with such idiotic rules. The decision to do so, through which they accepted those rules, is on them and them alone. If Baine didn't like that anymore, he could have left, joined the Alliance and lived the rest of his life as Anduin's foot rest as he always desired. Hell, Sylvanas herself wondered why he didn't do so at the start of BtS.
