You're in support of blatant fantastic racism because their ancestors supposedly "unleashed" the geth (who mostly killed only quarians and kept to themselves before the heretics anyway)? Would you support the same against the salarians, who unleashed the far worse Rachni Wars and Krogan Rebellions?
What instance are you referring to with the "O WOE IS ME" mentality specifically? I hear this a lot, yet the quarians never really do anything like that and all of them fully accept that their mistakes are responsible for their exile. You're perhaps thinking of the krogan with their constant ignorance of their role in the genophage and focus on how terrible it is for them, or the geth with their constant sob story excuses for both killing every organic they can get their hands on and allying with the Reapers.
I like this Quarian. Her voice carries the violet note of truth.
If anyone should be singled out for their ineptitude and general 'cry baby' behavior its the Krogan. They make no attempt to deal with the situation brought upon them by the Genophage (a situation that they brought on themselves mind you), and they continue to remain antagonistic, or at best brashly problematic, with the galaxy at large. And yet they (and the narrative) want's you to see them only as poor mistreated wretches that were unjustly attacked with the savage Genophage; an evil genetic virus deployed by evil, racist, jerk-holes.
The Quarians and the Rachni owned up to their mistakes. The Queen-Mother and her children join their chorus with the vibrant spark of the Quarians.
Indeed, including allied geth and trying to avoid a canon at the sime time would require an utter contrivance, but it's not as if they haven't done this in the past anyway (ignorance of Rachni decisions, inclusion of allied geth into the canon Multiplayer even though they can be wiped out instead of becoming allies with everyone else). I wouldn't put it past them including geth regardless.
Well to be honest, I would be willing to accept a contrivance in the MP if it meant that I could see playable Rachni, and the other 'less popular' races in ME:A. All of these species have tons of potential, I would hate to see any of that abandoned in favor of the select few 'fan favorites'.
