Well, if you don't want another civil war.
Either pick the group who believes that violence is not a valid political tool and work hard to ensure their victory is sufficiently overwhelming nobody denies it.
Or pick the group for whom violence, including political violence, has consistently been the answer to any question they can't lie their way out of and hope they never aim for you while you desperately attempt to ignore the dead piling up. Because violence is the answer to them, and I hope you realize that if they run out of conveniently available targets they will designate a new group to fit that role regardless of how insane the reasoning.
After all, it's not a civil war if nobody calls it one. It might just be a purge.
