Hi BG,
I think you missed the point. The scholar here is raising the issue how muslims are being asked sometimes stupid questions direct on their face by non-muslims. In his opinion due to these harsh questions muslims are tend to avoid talking to non-muslims or shying away with their responsibilities to clear their misconceptions.
He is advising muslims not to hide from non-muslims but to be more social and pro-active in explaining the deeen of Islam.
In the last of clip he says that even if some harsh non muslims insit you to answer this question that "Do you know how to ...?" then he put forward his suggestion which is to sit down with him for some time and explain him about Deen (Religion of Islam - the way of life).
Perhaps you can watch it again.
Regards
