They are meaningless words, because the views of a person are far more nuanced than that. But by labeling yourself as something, people immediately get to start assuming what your views are before getting to hear them from you instead. That’s the big problem with society today - everyone wants to be something unique, because we’re all so connected now that nobody feels like they stand out. But by adding labels to yourself, you just paint a target on your back for people to aim for, because with that brand new label, people get to make assumptions more easily. You get to be divided off from the “rest” of society, and put in a special bucket and targeted.
