The major assumption in the first sentence in the Declaration of Independence was the "all men were created equal".
This obviously wasn't the case because slavery was still in full swing; therefore, what was meant by it is that all WHITE men were created equal.
Here's one example of a 'free verse stanza of poetry.
"Who am I?" -
Who am I, you ask?
I am a lion who comes off as a lamb.
I am an ocean with waves big enough to drown.
I am a roller coaster of emotions.
I am a hater of ignorant people, liars,
And people who use others for a gain.
I am a lost soul, a naive child.
I am one who has seen enough
That would make most people's skin crawl.
I am me, not you.
I am who I am.
Judging me is only a negative reflection on you.
So who am I, you ask?
I am me...just me.
One identification of how my poem can be considered a free verse because many people go threw many questions and common life problems. People may forget what they are and what their life meaning is. So this can be a 'free verse'.
