Here is the difference, I look at things that happen and make assumptions based on that information. Some assumptions are positive, some assumptions are negative. Some people can't take reading a negative assumption as anything but complaining.
But there is a difference, a complaint is a statement of dissatisfaction. I am not particularly dissatisfied with the state if Iowa football. I don't think they will be particularly good for the next couple of years, but I don't think it is anything to get up in arms over.
But, for some reason people like you seem to get up in arms at my stating my opinion, which indicates that you may be taking this all a bit too seriously.
