I agree. It's a two-sided coin, the message/messenger dichotomy. Agreed upon "facts" can center on that independent of who posts them, while opinions entail the reputation of credibility and insight. It is interesting how society is changing now that we have the ability to react/respond with the benefit of time to formulate those, versus having more immediate responses and visual ques that denote an initial, and sometimes mostly emotional, response. I think it's a difference of just that; emotion vs critical thinking. We are evolving, like it or not.
