No such consensus exists, as indicated by this thread actually continuing.
Yep, and new books add new wrinkles, or explain old ones in sufficient depth to reignite the discussion.
There are things in Klondike and Liberation of Terra that show just how polarizing Kerensky and his invasion were in a Hegemony that partly supported Amaris. They also show how an entire generation of soldiers (much of the rank and file of the Exodus movement) reached their majority in training camps during a time of seemingly endless war, knowing a "normal life" only as some far off dream that would be realized if they followed Kerensky to the end....and then that dream was denied by House Lords that they knew mostly as fence sitters or suspected collaborators. Add on battle fatigue, mixed reception from the populace, problems with pay and stability, and the fact that the SLDF contributed to the economic destruction of the IS in order to finance its war, and you can see how the Exodus movement developed.
I personally believe that their reasoning was tragically flawed, but I think TPTB have done a great job of letting us see, in these new books, how it could have evolved organically among a group of real people, rather than just being a case of the dreaded "Author Fiat." Based on this, I can also see why some fans actually agree with the Exodus.
There are also new facts, on the other hand, that make one much less likely to forgive Kerensky.
For example, pg. 13 of First Succession War indicates that Kerensky's own journal seems to say that John Davion was amenable to Kerensky being First Lord. It also explicitly states that Barbara Liao was sympathetic, but refused only because the situation was too far gone. Jennifer Steiner was also supportive, but she could not give back the RWR worlds her brother had taken and Kerensky couldn't let that slide (IMO that was Alex's fault for not leaving a garrison).
I can see now that had Kerensky worked early for Capellan AND Davion support, plus giving more aggressive support to Blake and a hefty chunk of the Steiner populace that hated what Richard had done, and then spent more time doing things like undermining the supposed legitimacy of Amaris' election (part of the reason a fair bit of the Hegemony populace believed his war was illegal), he could have pulled it off. Even better if he had left a garrison in the Rim Worlds to deter Richard rather than trusting someone proven to be so selfish and unreasonable.
However, taking power would have required him to WANT to pull a James McKenna and he explicitly did not want power. He believed it was wrong to take it. Instead, in my opinion, he pulled a Ned Stark, and here we are.
