Plenty of nonsense in this thread, some sensible opinions (especially from Sparkey), but otherwise lots of fiction written in sub-par English and not surprisingly the content seems to correlate strongly with the language.
The Finnish I1 predates any known historical "Swedish migration" to Finland, this is easily seen in the fact that the area with most I1 - Satakunta - is almost 100% Finnish speaking (the areas with considerable historical Swedish settlement are still ~5%+ Swedish speaking and have more n1c1 than Satakunta). The Swedish migration to Finland happened much later than what can explain the Finnish I1 and is historically known. "The Swedes" did not "bring" I1 and western genes to "Mongoloid Finns". The Finnish ethnogenesis is far more complex than that and involves several waves of people and a pre-Finno-Ugric Finland before any notion of a "Swedish nation" either.
However, in my opinion and I don't think it is debatable, it makes no sense to say that "Finns were haplogroup I originally". "Finns" are a creation of I1 and n1c1 together, where n1c1 has nothing to do with being "Mongoloid".
