In this barbaric world, we need to understand what speech is. Speech is the expression of or the ability to express thoughts and feelings by articulate sounds. Freedom of speech is an issue to every country in the world. As what Sir Christian trying to relay on us is "we are all capable of speaking, expressing thoughts and ideas" and that is not just an essential to us but a skill/ability. A gift in general.
In analyzing, a world without speech to comprehend will lead to its apocalypse. A speech to express thoughts and feeling to settle the contentious relation between other ethnicity/country.
In fact, people used speech in violence, to harm other people, to create such an infuriating feeling to other people.
Everyone should be enlighten on how to use speech, language and expression correctly. Because we aim for Speech for serendipity - not for adversity, Speech for unity -- not for alienation and Speech for Peace -- not for Racist.
