Bangkok`s "gangs groups" seems to me a way of expression based on mexican cholo life style. This life style is what determined these groups in bangkok, but not at all. these thai men don't use violent traits or deal with drugs.  they can keep withn this life style, because Their behaviors don affect noboy. Everyone needs to express his identity, but only when we dont affect the society.

what has suprised me is that they have two different lifes, like the man who was a cop but in the night he was a real g ganster. No matter who you are you can exprees however you want. it doesn`t matter what people will tink about you.
