Social group and anti social group...sounds interesting... but would agree with Smoke...the tag "group" itself is suffocating cos it would then stretch to the thought of people of same mindset and that is where the problem starts when one starts presuming him/herself of a better (or superior) mindset than the other and at times even tacit racial feeling among members and then obvious likes and dislikes. Not necessarily though about here as I dont know, but saying based on being part of quite many groups which died down because of such issues and fragmented into smaller groups I was with in Dubai/Abu Dhabi.
