Because not everything is black and white in this gray world we live in. I am a professional quote maker.
Why no be yourself and just do what you do rather than define yourself as a title? There is no need to make things complicated. Sometimes it better to be vague or have a lack of adjectives. Like if one wanted to describe the temperature would say it is hot outside or hellishly hot, no wait it is freaking hot because it is not quite hot as hot or hot as hellishly hot.
Basically if you don't want to complicate things then all you need are few different shades of grey or a few select colors of a rainbow rather than several variant of colors to describe each niche.
