As far as the communists/socialists are concerned, all I actually wanted to say is that even among them there are differences, not all of them are Leninists, Maoists, Stalinists or Milosevic supporters. Even if they critisize NATO or the Hague court, it doesn't mean they like Milosevic or the kind of policy. I also wouldn't throw them automatically in the same bag as Neo-nazis that support Hitler and his policy. Especially since many of them don't promote a hateful, intolerant or even violent actions as is the case with the neo-nazis.
As for believing people, I would definetely research the matter on my own, no matter how close they may be to me in ideological views or in any other way. I don't take everything for granted, that's for sure.
On the other hand, proponents of failed systems, who carry their beliefs forward through historical denial and revisionism, hold no interest for me.
They are curiosities to be viewed for amusement purposes only.
And yes, trust is earned, whether talking about friends, pundits, government spokespersons, or even fellow Freepers.
