Some days before I was talking about an important thing with some of my friends. In the meantime a man came to us. I personally dislike that man due to his poor personality. He started interfering us. Basically I always try try to avoid this kind of people. But that day I engaged myself with him in a debate. He said that 'Mahatma Gandhi' is an animal. I could not tolerate him and his comment. I started arguing with him. And certainly I was successful. But this is not the matter rather the matter is after that fucking debate I was burning in that point that why I went to arguing with that person who have no acceptable knowledge concerning the legendary man 'Mahatma Gandhi'. I got a real lesson that I should not engage with that kind of people who never possess minimum personality and tolerance and minimum knowledge.
So, my understanding is 'Not to arguing with a person who have not minimum knowledge on the concerned matter/topic. It would be very harmful.'
