While I was driving today, I heard the BBC news talk more than once about Hamas, which Israel considers a terrorist organization (or some words very close to that). Now, look: Hamas IS a terrorist organization. They not only admit to many suicide bombings of buses, restaurants, and other purely civilian targets, they take pride in them. When you misapply your desire to be seen as fair by qualifying Hamas' terrorist status as just Israel's opinion, you sound much more biased, not to mention less factually accurate, than if you said the terrorist organization Hamas . Perhaps that's not a lawyerly interpretation of things -- it is certainly true that Israel considers Hamas a terrorist organization -- but to a normal person, going out of your way to specify that it's Israel's opinion implies that you think it would be inappropriate to say that it was a fact; and if a news organization is reluctant to say that something is a fact, that should mean that they have doubts as to whether it is a fact.
I have great respect for the BBC, but my respect for them isn't infinite, and it is diminished when they insist on giving those who take public pride in their villainy the benefit of the doubt that should be reserved for cases where the facts are actually in doubt. I don't think they are actually trying to be sympathetic to Hamas -- but it sure sounds like it.
