Of course in our parish Church here everyone would be too embarrassed to do anything like that, even if an over enthusiastic priest were to try to get us doing it.

Well, we've got Indians, Africans, Chinese, Poles, Irish, English and so forth, but not too many Americans... Just not our style.

Maybe sticking both hands up would be better - it might look and feel as if you were getting ready to do a high dive, but nobody could imagine you were doing Nazi stuff.

But if it doesn't mean it, it doesn't mean it. Treating symbols as if they held power in themselves over and above what those using them intend is a kind of idolatry.
