I agree, there are not groups getting together to speak for or against anything. Each posts an opinion. Sometimes that opinion is exactly the same as several others posting round about the same time. sometimes it is the diametric opposite.
Sometimes it is a comment of what someone else has posted as an opinion. So long as they do not insult the person posting what they disagree with, what is wrong with not agreeing with the majority? How else can the different aspects of a conversation be put before everyone?
Some people have right wing views, some left. Some people believe all that publicists say, some believe all that teenage girls say. Most can judge for themselves what is/has been going on.
