Agreement or Disagreement comes with supportive explanation to make a justice for the statement put forward by the individual. Most of the time Agreeing or Disagreeing has flavours, these are "To avoid controversies", "personal or collective agenda" and most important fuelling of EGO because some people has to say something regardless of their knowledge about this topic or situation, because these so called "Sentient beings" believe their opinion makes a difference, but in reality it is really not required, similar to my statement made here.
