yeah, i guess with that definition of subculture, theres no porblem with anime as a subculture. My statements were based on the definition I was taught for subculture:
"A culture-within-a-culture; the somewhat distinct norms, values, and behavior of particular groups located within society. The concept of subculture implies some degree of group self-sufficiency such that individuals may interact, find employment, recreation, friends and mates within the group"
