You're not. I'm also almost blind on one eye (perfect peripheral vision, so no depth perception problems, but forward vision is around 20%), and 3D simply doesn't work for me, regardless of the technology used.
I'm not exactly concerned about exclusion, yet. I've watched the 2D versions of most recent 3D movies (Avatar excluded), and thought they all sucked. The only thing going for them was the 3D gimmick, so most people (my wife included) liked the visuals and felt they got their money's worth; for me, not so much.
I know at least 2 other people with the same condition I have (1 relative, 1 co-worker), and several others with various eyesight problems that prevent them from fully seeing 3D movies.
I doubt (at least hope) we'll ever get to a point where 3D stops being a gimmick and becomes an integral part of the movie (like... needing a 3D view to fully understand a scene), at least until holograms (actual 3D projections instead of visual tricks) come along...
