Nuclear-powered lighthouses are critical to the aff, just look at the plantext. If you have a problem with someone telling you what their aff is well ahead of time because they want to debate people on the merits of their aff rather than generic debates that happen every round, then more power to you. I don't care what you, Steven, Chris, Andrew, and Colin think unless your opinion comes out in a debate against me. When people just think of one thing, like "Avatar" they think, "Oh yeah, we just go to Pandora and colonize it, steal resources." without thinking on their own about what that means, much less what the real message was (the exact opposite.) Think about nuclear-powered lighthouses and predict what the argument I'll be making about them is, and why we should build them. I may have not considered one standpoint on it, and if a team is passionate about that and beat the substance of the aff, then it's worth it. It's not meant to be necessarily in my interest to do this, but in the interest of good debate.
