a lot of lot of horrible, horrible stuff that I never, ever want to be associated with.

As a lurker and relatively new person to this community I've now seen this sentiment expressed multiple places but without any specific examples. Could you (or anyone else) please provide some? I'd really like to know more about this before I start talking about Less Wrong to my friends/family/coworkers/etc.

Feel free to PM me if you don't want to discuss it publicly.
