In order to feel safe expressing your opinions, you have to feel like you won't raise an eyebrow. Either that, or any owner of a raised eyebrow won't take it any further than the mild disagreement of raising an eyebrow.<p>It's really obvious that not only is it not possible to say whatever you want at work, but that in some cases, raising an eyebrow is the last thing you will ever do, at least within the context of one's career.<p>The tension at hand is founded in things that simply will not be happening any time soon. But unpredictable reactions to minor slights set people on edge all around.<p>The polarity is highly charged, even though no one really has murder and beatings high on their list of priorities, the paranoia and suspicion that the other side <i>does</i> is what leaves us destabilized.<p>Homosexuality, abortion, race, evolution, genetics, how the universe began, and where do we go when we die. Talking about these things at work is a mistake, but even joking about "the wrong opinion" will completely ruin you in less than an hour, so trying to feel safe about having an opinion is a bad idea, whether you feel you're on the right side of history or not.
