ah, there's a paradox hidden in there. Journalists are not one homogenous mass. A journalist is essentially anyone who condenses and reports information (hopefully facts) to others. If you got excited about a given issue (oh, say, journalistic ethics) and put some effort into researching it and shared wha you learned, you'd become a journalist.
Isn't that a wonderful thing? The internet means it's available to all of us to be both citizen journalists and citizen politicians - politicians are simply people who have a point of view that they seek to gather people around. So it makes me sad when people say the problem *is* journalists, or the problem *is* politicians. It's not - the solution is good journalism and good politicians.
Support good journalism (subscribe, whitelist), support good politicians (yeah, I know. But if you look hard, there's someone out there saying something you agree with that is thoughtful and persuasive), denounce the bad ones. Don't tar the entire group with a brush because that is cynical and self-defeating: the least likely way to make the change that you want.
