DLFan2 makes a great point, and that's why I'm active in this forum, but it doesn't address the quote included in the OP.

Using derogatory terms to discuss DL or PAX behavior may be therapeutic, especially when puked from behind the curtain of anonymity, but it's neither productive nor socially redeeming.

For example, I'd never say "puked from behind the curtain of anonymity" to my mother. (Sorry Mom!)
