The intricacy of incest

Is incest really as wrong,as tainted as it's made out to be?
I am lost for words,to describe what I think and feel.
If it's a feeling,an act of consent,why should be adjudged immoral by society?
Love does know no boundaries,
The risks are many of biology,
As they say too for homosexuality,
but why,do we let convention decide how we breathe,
Noone chooses love,love chooses them,
and how is it any different than a choice we are all entitled to?
Who are we to decide and dictate what to feel and when and for whom?
We were born free,they say,then why can't we just be.
And why are our minds framed to think so conservatively,
why as children are we not allowed to ponder free?
We're young and we believe we're the change we want to see,
but almost two decades of rigidities are hard to unfreeze.
We question what makes us feel what we do feel,
but we forget to question if our ideas can change completely.
Why is it that marriage in kin is an acceptable form ,why only consanguinity,
but out of wedlock,it is considered "sin against humanity"?
Leave alone society,leave alone sin,and biology,
is it still a question  of morality?
What makes us make that choice that seems an anomaly?
Mere absurdity,or is it reasonable rationality?
Is incest really as wrong,as tainted as we are made to believe?
