Does anyone else believe in deliberate alienation? Forums and organizations like Lesswrong often strive to be and claim to want to be more (and by extension indefinitely) inclusive but I think excluding people can be very useful in terms of social utilons and conversation, if not so good for $$$. There's a lot of value in having a pretty good picture of who you're talking to in a given social group, in terms of making effective use of jargon and references as well as appeals to emotion that actually appeal. I think thought should be carefully given as to who exactly you let in or block out with any given form of inclusiveness or insensitivity.
On a more personal note, I think looking deliberately weird is a great way to make your day to day happenstance interactions more varied and interesting.
Yes, insufficient elitism is a failure mode of people who were excluded at some point in their life.
If it's worth saying, but not worth its own post, even in Discussion, it goes here.
