I'm actually very distressed about DanAllen's comments. I think they reflect poorly on both our professions.
I'm not understanding what distresses you. But to be clear, while as the architect I do set the design and location of the building and elements within, I do that as part of a team of engineers, designers, the owner, etc. We generally intend to work with, collaborate, take input, ask for recommendations, learn from, etc, all the disciplines on the team, structural, civil, landscape, MEP, lighting, acoustics, you name it. But ultimately I am responsible for coordinating all the work with the architecture, and that usually means reviewing and redlining drawings as part of coordination. I understand there are hacks in every field, but on my projects, for the civil to discount my drawings because "structural dictates" is just wrong.
