Yeah, I kind of agree that we assemble planes, be it kit, arf or otherwise. Scratch building would be just that, building.
Like a house. You build a house from plans. That is, you start from drawn plans, and from a pile of lumber, you cut each piece of wood to length (or to spec) and build.

Thinking about it, I think I generally say "I put that kit together" so it seems to translate to assemble more than build.

But, whats the real argument here anyways..

I think its Obama's fault.
