1) The statements "The Geth killed billions" and "the Geth exterminated everyone who couldn't be evacuated from Rannoch" are two different statements. One does not logically imply the other.
2) Are you serious? "Of course, if we can cure the Genophage and put a stop to the endless stillborn dead babies, that would take a priority over any societal reforms." The idea that Wrex would not pursue a cure for the Genophage when one is available is not realistic.

1) You used the word "hate" originally to characterize how you thought Shepard was defined, so I responded with the same word. What I should have said was that you're projecting hate onto Shepard - but "hate" is a reasonable and natural response for Shepard to have. In a similar way, you can project other feelings on to Shepard with respect to Cerberus, just not active current support.
Why you would not hate the organization that, among other things, raided Grissom Academy, executed the Citadel coup, and stopped Shepard from gaining secret of the Catalyst on Thessia is your own business.
2) I can easily see a character being forced into an unexpected, perhaps even unwanted, dream as part of a tabletop RPG for roleplaying purposes, so I don't see why it would be an issue in an RPG video game.
3) Its true, I do think this point as ridiculous. My original question was: what POV are you suddenly unable roleplay? You brought this up, but it is something you could never really do, hence ME3 is not exactly suddenly worse at this with respect to be the other two games.
Mass Effect 2 is a story about a squabbling combative crew that has to be made to work together for the Suicide Mission. Because of the conflicting beliefs certain members would become alienated based on Shepard's decisions. That isn't the story of the crew in ME3, hence you can't get the same interactions from them ( aside from behaving in such a way as to cause Tali and Wrex to die). My point is that, in and of itself, the relationships that Shepard forms has very little to with defining Shepard beyond to the opportunity to allow Shepard to make a decision. We've already had the story where companions got annoyed in ME2 based on decisions. ME3 is a different story. Shepard is defined by decisions he makes, and there are plenty of those to be made in ME3.
4) We have the ability to RP to a high degree in ME3 - you are just asking for more.
I've played Renegade in all three games, and I never got the sense that I was telling Hackett, or Anderson, or the Alliance any of the stuff you're talking about in ME1 and ME2. But for the sake of argument, let's just assume that you could do that in ME1 and M2. In ME1 Shepard has a Specter mission, and is constantly side-tracked by Alliance requests. In ME2 Shepard is working outside the Alliance and Council with a known terrorist organization. In these two stories there is opportunity for Shepard to come into conflict with the Alliance, so that would be why Shepard could decide to do so. In ME3, the story is that the Alliance is supporting you and your decisions to gain support to fight the Reapers. Telling the Alliance off would essentially be b****ing to Hackett, the guy holding the remains of the Alliance fleet together, or Anderson, the guy running the resistance against the Reapers on Earth. I think your request is unreasonable, unsupported by the story in ME3, and needlessly confrontational. I don't see any reason why Bioware owes that behavior to any player in ME3 for roleplaying purposes.
