Liike people doing cosplay for villians or kids dressing up as pirates, demons, and ghosts for Halloween, this is just a concept not a mass media campaign for serious criminal organizations.
Besides, most of the topics in the songs are based on righteousness, integrity, honor, and being awesome...kind of what the initial triads in early Chinese history promoted (they did not start out as a criminal organization). If you want more info on that, see "triads" on wikipedia.com
As for Dustin's remarks....I mean the band of course is being taking seriously, but you probably shouldn't worry so much about life in the message boards. Like I said, if more than one post about iyt bothers you that much, request it to be taken off by a moderator or just don't read both.
