A building is engineered, and automobile or even a wheelchair is engineered.
To call a person engineered is a cold and heartless degradation.
The Latin words for this figure of speech is conde censio or in English it is condescension. Giving a human the characteristics of a machine. A human is like a machine rather than a human. Like a static non thinking, non human cold and sterile thing, lifeless thing. You dehumanize and degrade its worth so you can discriminate. Discriminate from humanity so you can discriminate from service and the military.
You could have gone the other way and given a human the characteristics of a God. Like calling a transgender person "divine", angelic or celestial even a phoenix who has been transformed like a butterfly and survived the fires of hatred. This makes them a tough and hardened soul perfect for the battlefield.
The lowering of a person by the use of conde censio you might as well call them a piece of dust. Using DNA as an excuse to lower a person's humanity is a cop out. Well they are just a jumbled bunch of code so they are engineered. For an engineer you certainly seem uneducated in the most rudimentary fields of respect and decorum.
In the reverse, saying the ground was thirsty or the engine roared, raises an inanimate object up to the human level or giving God human characteristics like, God saw or written by the finger of God lowers God down to our level.
It is defamatory to refer to a human as a machine that is engineered. It seems that you are using figures of speech to elevate yourself but contrarily it in truth it only lowers and demotes yourself down into the dirt. The more you speak the further down you go.
