DAP...who are they really?

This was forwarded to me earlier this evening. I listened to it twice, and it made me think....if this is the kind of video that is making the rounds on social media, no wonder the Malays are thinking that DAP is indeed the devil that they have been made out to be by Umno and Pas....and yet, at the same time, this Rao guy was once with DAP. So is there any truth in what he says?

Can anyone enlighten us on the veracity of what Rao says? Either way....
