In my opinion the most important human right is to be ´´free to say what you desire´´
Every person should have the right to express the way that they feel because each and every individual has their own personal mindset & should have the ability to make their own decisions.
There should be no reason for a person not to be allowed to express what they feel and want to say because everyone controls their own atmosphere. Also, nobody should be able to control one anothers word per say.
One might say this because they might think that they are above one another and take advantage of the fact that they have more overall power than you do yourself.
It's important to defend freedom of speech because every single individual is born with the right to verbally express the way that they feel and to tell people how they think they should be treated.
