I too, am pretty much nihilist. People don't like it because it sounds depressing and because they think nihilists become sociopaths. The former is understandable, but isn't really saying anything other than 'ew'. Well, it can be meant to say that since it's depressing, it will make nihilists depressed, and they don't like that. Somebody famous (might've been Carl Sagan) has some quote responding to a religious person asking him whether being atheist doesn't kill the mystery and wonder to life. He says either that it does nothing to hamper his sense of wonder or that it actually magnifies it, because reality is more interesting and engaging when we believe there is some intricate framework behind all of it and we can make our modest attempts at unraveling it.
The idea that nihilists turn into sociopaths is pretty absurd. I'm willing to bet that some nihilists would even take offense at it. Sure, it's gonna corrupt a few people, but not many. Nihilists are people. They have feelings, they care about things. They just believe that their cares are of no objective meaning. Even though I don't think Bill Hicks is a nihilist, I'm gonna make reference to his "Life is just a ride" bit anyway. It's a great example of someone making the argument that, while life doesn't really matter, that doesn't make life any more depressing, and in fact can make it a lot less stressful. It's just the "this too, shall pass" attitude, really. Sure, some people will use the mentality to be bad, but isn't that really a product of their character/tendencies?
The reason academia doesn't talk about nihilism-in addition to the fact that people dislike it-is probably that, well, nihilism is the end of the line. There's really nothing to debate besides its basic principles and no way in which it could change or grow.
I'm a nihilist and I'm kind, emotional, and have a sense of wonder that can sometimes just be plain overwhelming. I realize that some can do bad in the name of nihilism, and I'm fine with that. Nihilism is the most defensible system of belief in my opinion. Besides, what's the difference between someone who commits bad actions under the nihilist banner and one who acknowledges no belief system and commits bad actions by just saying "Whatever. I do what I want"?
