I don't think it's an Iconolast's alt only because it's a dumb choice. PJP doesn't post regularly, hasn't in some time, and probably wouldn't do much in response anyways. Plus, creating alts of family members doesn't make any of us fly into the gay rage that mark the Iconolasts' whole reasoning to botch-"raid." I'd like to think they're smarter than this.
Of course, it could always be one of them responding to the brilliant and hilarious new "Sikkbones" alt (complete with picture). Which would be unintentionally hilarious in its futility.
Dude, you're talking as if the Insurgeolasts use any actual form of logic or reasoning.
