The thing with 'bias' is that pretty much any issue with any opinion - even if one is 'right' and one is 'wrong' - is attacked as 'bias' if it doesn't treat each equally.
Is being anti-slavery 'biased'? What if this were during slavery, and you said 'slavery is wrong'?
Well, you're just 'one side' of the issue, and anything that doesn't treat the pro-slavery crowd with just as much time and respect as your position is 'biased'.
When something gets enough consensus, the media can side with one side and not have the public have a problem with it, the funny things is they're often wrong, too.
The 'consensus' on Vietnam an 'unbised' source would have is a lot different than the 'consensus' later. Or with Clinton's finance industry deregulation.
You want opinion. Without that you don't get 'Vietnam is bad' or 'good'. You get 'there are x men and y American casualties and z Vietnamese casualties and people said things.'
Reading from someone who has been to Vietnam and provides informed commentary that has opinion, is the most important thing for you to read.
It's up to you to separate the right from the wrong, which isn't as hard when you learn about who has different motives (see my sig for better things).
'Bias' is a mountain out of a molehill - it's a lazy way of attacking opponents without proving your point. It's very real, with 'paid for' opinion, with the propaganda machine and the industry paid to push a view, but even that's not best described as 'bias'. Things you agree with, it's hard to see 'bias' in as well.
This is a reason change is hard - the civil rights movement seemed radical, communist, threatening to people who were used to 'how America had always been'. Anyone for the civil rights movement could be easily viewed as 'biased' - and vice versa by 'the other side'.
Is the radical right who are pushing an agenda to put the US back a century 'biased'? Are those who expose that agenda and criticize it 'biased'? You have to decide.
