Is that supposed to be a known concept?
Also, while I think NAMBLA ranks among the least popular sociopolitical organizations among Americans of any political stripe (those who know what it stands for, anyway), I really can't see how the NAMBLA statement can be considered a "seemingly right-wing tweet" by any standard.
Anyhow, the whole thing is rather sad - trolling on Twitter shouldn't exactly be considered an achievement, and as for "hilarious", I suppose there's no accounting for tastes.
