You're definitely not expected to eat the ginger along with the nigiri (sometimes menus will point this out) but, I mean, if you like the way it tastes, go for it. :)

The only thing I think we have to agree on is that people who mix wasabi in with their soy sauce are evil.

That sort of makes all the fish taste the same or very similar.

I can see the appeal, but I think that would overpowered and confuse the mixture of flavours.

Heh yeah I eat a ton of that ginger all throughout the meal

I eat sushi without ginger, wasabi or soy sauce. Yuk, yuk and yuk.
