“A map IS not the territory” – Alfred Korzybski. The word ‘is’ carries the risk of identification. The word “is” easily turns a description into an identity.
Those who forget this confuse words with reality and rule out change.

My skin is light. I am not my skin color. I am not white. 

Writing is what I practice. I am not a writer. My profession is not what I am. Let alone a stay-at-home dad.

I eat meat regularly, and sometimes without. I am not a flexitarian. I am not what I eat.

I sometimes break promises. I am not a bad person. What I do is not who I am.

The word “is” is often used inappropriately. Port-modernism, in particular, has attempted to change this. People are often given labels, and in various languages, not all of them, people are defined by these labels. Wrongly. A person is not a label.
