Labels are used to separate and arrange things, so as not to cause confusion. Labels serve as a means of differentiation.
Labels are good for things that are non-living, but when it comes to people, labels aren’t really the way to go.
Labels, like I said, create separation which creates discrimination, labels force people to choose a side, and in most cases it chooses the sides for them even when they are not ready.
Human beings are constantly evolving and sexuality is a fluid concept, giving it a tag might in some cases be limiting.
