Exactly - labels can be useful and handy as a practical communication tool but more often than not they become limiting factors to our perception of self and the world (i.e. "others") and have a negative effect on our inner freedom, motivation, compassion towards fellow beings... They are often a result of limiting beliefs. Thus it is much more useful to at least attempt to be mindful every time one labels sth and even more so if it is not a "something" but a "someone"...
