Giving Dawah is like sales pitch for these Muslims, they have a a set pitch that aim at people and like the guy in the video he is desperate for a sale and the frustration really gets to him. I've seen this a lot in videos you get these Muslims that just can't understand why people don't agree...
It's a complete brickwall with Sunni Muslims the Aisha/Muhammad issue, the whole "thighing" of Aishia is also ignored and not talked about. You will get a lot of "Well.. it was just the period of time everyone did that then.." kind of answers from Muslims or "it was a special relationship"..
