"I'm not trying to be some kind of underground renegade"

In this quote, Alex Winter is expressing his desire to not be viewed as a rebel or an outsider. He is emphasizing that he is not attempting to be someone who is deliberately going against the grain or challenging the status quo. He is rather attempting to be a part of the mainstream and to be accepted by the bulk. This could be analyzed as a desire to suit and to be accepted by society, or it might be viewed as a desire to be viewed as a leader and to be respected by his peers. In any case, it is clear that Alex Winter is not attempting to be an abandoner or a castaway. He is rather trying to be a part of the mainstream and to be accepted by the bulk.
