The INTP's drive towards anti-socialization, is one of the INTP's strongest social behaviours.
An INTP does not easily inherit the norms, customs and ideologies of their peers. They have an inherit need to deviate from those and create their own norms, customs and ideologies. This behaviour is almost constantly present within the INTP. As a result of this behaviour, the INTP differentiates itself from the social norm and is often seen as an anti-social hermit of sorts. Like a smeagol in middle earth!
However, the drive that results in this behaviour is inherently social, as it attempts to question and improve on broadly accepted norms, instead of blindly following them. In order to better society for each and every one of us!
So one could say, the INTP's are the pioneers of future society, today! (Slightly sugar coated it there. I tinny bit. >.> )
So INTP's are in fact very social creatures. Argueably even more so then some other types who are considered social by the current norm!
