Self-Defense is Natural Law

"Trust in God, and keep your gunpowder dry." - Oliver Cromwell

Nature is life.

Nature is alive.

Nature has some defense mechanisms.

Animals have some defense mechanisms too.

Defense mechanisms are imperative in preserving life from the beginning of life on earth.

Many organisms have adaptations that help them prevent predation.

In addition to escape strategies, hide and defend.

From the simplest organism to the most complex.

Camouflage is a technique used by several animals.

Used to self defend or to attack.

Cryptic coloration which consists of the fact that the individual has a pattern and coloring similar to the environment in which he lives, confusing his predator.

Like mantisof flowers are the species of praying god that imitate flowers.

Powders take on different shapes to camouflage.

Chameleons change color.

And some animals have harmful chemicals and these can be advertised with a color pattern called warning coloration or aposematism.

Like beetles bombers are insects that shoot jets of a supernatant from behind when they feel threatened.

And the false coral snake presents coloration similar to true coral, yet does not inject poison into its prey.

But then self-defense is a natural right?

Yes, because it emanates from an automatic defense response of our body.

This is the instinct for survival  present in all animals.

That we see in some beings still babies.

And it is this instinct for survival that makes self-defense literally vital.

Essential.

Irreplaceable.

Imperative.

Because no living being wants to die.

Everybody wants to live.

Survive.

And for the animal to survive, it will need to know how to defend itself from predators.

This is self-defense.

Try Survival.

Try to avoid an attack.

Or get out of it.

This instinct is rooted in the core of every being.

We were born with it.

It is a natural gift.

For living.

And keep living.

Addendum

Note important in my opinion, because i can not have been clear:

Self-defense does not necessarily mean using violence. 

Fleeing and hiding are also forms of self-defense.

I ask a question to those who criticize and disagree:

Would you let someone hurt you physically?

 √ Will you be inert suffering? 

√ Are you going to run away? 

√ Are will you react?

√ Are you going to hide?

I doubt you opted for the first answer.

You know what you are do not you?

Hypocritical or Sadomasochist.
