I'm pretty sure that by "outsiders" he means all people that are not native americans (all colonists basically). I think the reason is that he kills british soldiers is that most of the game takes place at a time when the british are still ruling america and thus being the predominant guard type.

I also think that as an assassin, Connor should be able to look beyond ethnicity and do what's best for all humans. It is possible, though, that a major part of the story will be seeing Connor go from an angry vengeful boy to a mature assassin who lets go of his hate and does the greater good (for europeans and natives alike).
