There's basically two reasons to get called arrogant. One is acting like you're better when you aren't. The other is refusing to politely pretend that the inferential chasm is small. Given where E is and where the mass of humanity are, if I had to make blind-guess assignments for 100 accusers picked at random, and I assigned them all into the "inferential distance" bin, I don't think I'd be wrong once. So, a person asking to be put, or to put some accuser into the "undeserved airs" bin, had better show some sharp evidence!
