That video was made by someone trying to stir up some shit. He/she calls Zakir Naik a loser and says things that only someone trying to demonise Islam would say but all of those techniques mentioned in the video are very very very very common.
Really clever apologetics have more tricks in their bag. There is a really clever American Muslim convert who sneakily presents himself as a non Muslim debunking the critics of Islam.
I heard him deflect criticism of Mohammad's days as a bandit by saying that in those days caravans could be as long as five miles and that Mohammad only ever commandeered the camels straggling at the back and never actually used violence. I thought that was pretty clever, he seems like a nice chap. I will post one of his vids at the bottom so you can see a pretty good apologetic in action.
I find it funny how anyone so intelligent could convert to Islam as it is plainly a load of bollocks but a combination of differing scriptures that can be used to back up the Koran or be dismissed as unauthentic when they don't help the cause add the claim that you must speak Arabic to truly know the Korans perfection, sprinkle on a few conspiracy theories, a dash of 'science' and a handful of 'experts' to back up the 'science' Now quote some peaceful verses and you have got a force field that nothing can penetrate.
Islam is bullshit but it's hermetically sealed bullshit.
Check this guy out he is an accomplished apologetic.
