What's the point of twitch chat anyways?

Seriously... all you see is predictable and repeatable short words like every time someone made a little mistake the chat just goes "LUL NA Flash!" literally all the time. I understand that the chat is going way too fast for long sentences to be readable but you keep seeing these same exact words every time a mistake happens. Even racism appears on chat whenever a non English speaker is being interviewed. It's disgusting... Do people actually find it enjoyable to read these when you know what they're going to say because its basically an open book.. I was honestly offended whenever someone talk about my language being an "ugly language" on chat. >.>
