I voted non-Nicene, but not for reasons of political correctness. The prefix "anti-", while it can mean "disagreeing with" and thus would be accurate, in the popular mind also tends to be "opposed to", which has a much more polemic flair to it.
So for example "anti-abortionists" are those who not only disagree with abortion, they also are usually those who go out and fight against abortion legislation.
It tends to be an active descriptor, whereas "non-" can merely mean they disagree or hold different points of view. I may think non-Nicenes are mistaken, but I do not think the majority of non-Nicene believers actively go out and attack Nicene beliefs (except, of course, in debate discussions like these forums, and over coffee and such). Some do, of course... JW and LDS both have strong traditions of door-to-door soliciting to try to convert others to their way of thinking. But there are many others who just hold a few non-Nicene beliefs, and don't think much of it. Like annihilationism, or preterism, or Nestorianism, or all the many little things that one can believe that are contrary to the Creed, and still function very well in a Nicene congregation for years, sometimes without even realizing there is a problem with your doctrine.
