What does it take for us to be repulsed by a certain phenomenon? Well a person would, on the surface believe that this is just because the way they are. However, what makes a person who they are is a composite and intact form of a life’s history and its own little magic map that shows it possible outcomes for the future. So at an instant a person’s likes or dislikes are bound by their position in their own perceived continuum. We are all time travellers without even knowing it.
There is little doubt about the fact that different people like different things, and sometimes some people may dislike others for what they do or don’t like. The only question would be if there is a benchmark for acceptable affinity with a particular thing or event. Perhaps there is no real answer here, because it changes with each individual sequence of choices and circumstances resulting from other choices and factors that make up a personality.
The scents and smells, the feelings one goes through when lonely, the anger or fear from a past or imagined event and the sight of something that just doesn't sit well without any apparent reason. These are all linked and controlled by the human condition that may or may not be controllable by the individual. So what’s the likelihood of disliking something? The resolution is somewhat similar to answering the question whether feelings tell us how to react or we feel the way we decide to react.
