Why so many gloom and doomers on this site

So far I haven't found more than a very small few that don't want to make you scared or angry about something.

They just differ in what that is.

I agree and disagree with this point. The most popular news sources are definitely driven by the fear/anger model...look at the scared shitless preppers in this thread! But this doesn't mean that we should just throw our hands up in the air and let someone else tell us who to vote for or how we should live our lives. It is possible to find news sources out there that are attempting to convey facts without telling you how to feel about it.
