My thoughts on this video:
By making fun of teenagers, this guy has successfully marketed the idea that people should speak without a hint of skeptical modestly. As if "conviction" meant blasting messages loudly and proudly without caring if there is any truth behind the words.
Staying open-minded to being wrong about our beliefs is not something we should mock people for.
If only MORE people were willing to say that they could be wrong, willing to accept that there could be a flaw in our own logic, we might live in a society more prone to compromise, to listening, to trying to understand one another.
The message he's sending is one of aesthetics. He feeds you his message by making you agree that the way people speak sounds bad. It doesn't please the ear, therefore his audience agrees that he must be right about his message. The real message, folks, is about advocating divisiveness.
When two people with different views speak loudly and confidently, when they blast each other without acknowledging that there could be other opinions, those two people will argue, not converse. They will fight, not find any sense of mutual understanding.
What we need is MORE people willing to admit when they get something wrong. More people open-minded to the fact that they might not be correct. Sure, the way teenagers often use wish-washy speech sounds bad, but it's not a bad thing to speak with modesty rather than bluntness.
