Historically, political parties have espoused one ideology or another. Party members have cherished beliefs. They fight for their sacrosanct values; ideals that are automatically defended.
Interactive Democracy encourages debate, issue by issue, and takes a step away from left/right party politics. There is less need for anyone to tow the party line. This concentration on each topic will engender a more detailed examination of the facts and encourage scientific study of the situation even if some arguments are based on ideology. It could be a step away from emotional knee jerk reactions.
