hmmm, everybody has been mis-informed at least partially on the subject, there´s way more behind the curtains than what both sides have been fed with (well, i guess every war ever fought and documented has been mis-informed one way or another). Nonetheless, I do believe the only feasable way to win them back is by having kelpers wanting it so and that can only ocurr when and if we ever have a decent way of living and oportunities for everyone (including kelpers of course). If being argentinian means opportunities, better jobs, high education (and free as it is now) and all sorts of other advantages they may decide some day it is in their best interest !
Of course, this is marely hipothetical and if it ever happens, it´s in the far future heheheh.
You can actually have a decent conversation with many locals on the subject, we´re not neanderthals here heheh !
Goes without saying you would not have any problems here for being English, there´s currently many ones living or just passing by or that have brit heritage and I dont believe (for the most part at least) they ever encountered problems on that account.
Almost everybody here, specially in BA know the difference between Ireland, Scottland and England (well, they know only the basic ones, like they are different countries..in a way heheeh) what´s hard for most (not all though) of us is being able to tell the difference between accents and which one corresponds to which country (hence..they all look the same and speak sorta the same hehehehe). Also keep in mind our society has been influenced in many ways by Irish, English, Scotts and Welsh (i do have irish blood in me so they definately had influence in me been here
Anyway, dont avoid the subject neccesarily and if you actually have such conversation, even if you disagree, just try not to tell the argie at hand that he is an idiot and ignorant and that what you know is absolutately the truth and what he/she knows is absolutely garbish, that may not end up well (wherever you are wherever you are from)
