Origins of thoughts / ideas always interest me. Maybe, he is also interested & trying to explain those.
When I was really young, I & my friend ridiculed the thoughts of an elderly man (not to his face). We used to laugh ourselves thinking he was eating our brains. But after some years & wisdom, I see the point in all that gentleman's thoughts. I regret ridiculing his thoughts. Actually, I was also in university when I did that.
Also, unless you are carried away by the comments from all pakistanis (they can create many reasons to laugh at India), his talk is not that bad / ugly. I would say that talk has some unwanted / unnecessary sentences. Maybe, he is a small time poet, and tried to use those skills. Also, he appeared confident and in command. That is my impression.
PS: maybe, you are young and find still find that talk (given at your college) all BS (or) maybe, my interest in origins of everything is not of interest to anyone. I am not judging you though.
