I agree there's no reason to make an exception for GMOs. I extend that logic to labeling though. There's no reason to think GMOs are inherently more risky as a class and should therefore require additional labeling. GMOs should have to go through the same FDA (or whatever equivalent various nations have) testing as everything else, but labeling everything that was GMO as a GMO thing is going to cause people to make uninformed choices based on fear instead of good informed decisions, which is counter to why mandated product labeling exists.
