I am subjective about things in which objectivity is not applicable. Pineapple on pizza for example, there is no objective answer.
Food preferences are not always a choice. There is the food you grew up eating which instilled biases and skewed opinions. There is the cost, which might mean you pretend to like the things you are forced to afford out of a lack of options. Then there is the physiological, where you might have allergies, problems tasting certain qualities that everyone else can, etc. So, no, there is an objective facet to food preferences.
But, that's totally beside the point. What you eat doesn't interfere with the quiet enjoyment of others around you.
Yours is a self-centered, narcissistic opinion.
Everyone eats, but not everyone lights fireworks and terrorizes dogs and cats while also causing breathing problems for some of us.
Basically, you are ignoring the objective facts because you want to side with the subjective desire to have fun.
Glad the rest of the world is not as "objective" as you are....
