In reply to David Riley:
I'm not sure that further poring over details is going to achieve much but I think it is pretty much impossible for anyone, including you and I, not to be influenced by media propaganda.
Furthermore, everyone likes to feel pampered by hearing further support for what they already believe to be true, whereas considering reasoned argument to the contrary can be uncomfortable. It's not surprising that people will tend to avoid uncomfortable situations.
Your last paragraph doesn't make a lot of real world sense. Nobody arrives at opinions purely from raw data. Everyone builds opinions based on news reports, opinion pieces and constructed argument, ideally a mix of things you expect to agree with and things you expect not to. The important ingredient is not to dismiss reports, opinions and arguments out of hand simply because they suggest something different from your existing opinion or belief. The first requirement of that is for opposing views to reach you in the first place, the second is to give such views a chance and only dismissing them as lies, biased, irrelevant or stupid if you feel you have have rational justification for doing so.
