I would add that a lot of us who were born or grew up in the UK are quite comfortable saying stuff like "you're right, but...", or even "I agree with you, but...". The British politeness thing, presumably.
0-24 in the UK, 24-62 in the USA, am now comfortable saying "I could be wrong, but I doubt it" quite a lot of the time :)
