I'm one who tends to shy away from labels, and can get an instinctual, averse reaction to people using certain labels to describe themselves. For me, it's because they can place individuals, either in their own perception, or others, into a little box, and people are more complex than that.
If I ever do use labels, they tend to be along the lines of independent, or individualist. I can be various things at various times, and separate that which I do/like/am from the entirety of 'me'; ie, I enjoy this, but not that I am this. However, some, such as me stating than I'm an Atheist, or male, I see as simply either/or objective statements of fact, and differentiate between those and more subjective, fluid labels.
