From the video I can only guess that it must have been a traffic related conflict and the victim is a mere teenager/kid while the attackers are fully grown men. In a country like India such brutal attacks in even minor traffic related conflict is normal. Some disturbing points to note:
1. The attackers do full beadbi of the Kesh of the Sikh kid. All Indians know that the kesh of a Sikh is sacred. So pulling it was a deliberate attempt.
2. Before getting to his kesh, they must have knocked off his Dastar. And again, all Indians know that the Dastar is the symbol of Sikh identity and pride. So going for his Dastar was also a deliberate attempt at humiliating his disrespecting his faith.
3. You can see a few Sikhs standing there, but not one has the courage to intervene and help a fellow Sikh in distress. This is what I find the most disturbing. When you can see a Sikhs dastar being knocked off and beadbi is being done of his Kesh, your blood should boil in rage. But not one reacts. Would puratan Singhs like Baba Deep Singh Jee, Banda Singh Bahadur or Akali Phula Singh have just stood there and watched like a helpless spectator? Khalsa of old were helping non Sikhs in distress and fighting ferocious Pathans but today's Sikh cannot even defend a fellow Sikh against a tobacco chewing Hindu. This has got to be our lowest point.
Some Sikhs today still fight back like this Sikh truck driver who retaliated and these cowards all ran away:
another case is this:

In this case this Sikh man was attacked by mob. When his dastar was knocked off, he retaliated by killing one of the assailants and sending another one to the hospital. Some of you with your western values may think this is wrong, but if this Sikh man and the Sikh truck driver had not reacted the way they did, they would have ended up just like the Sikh kid in the video who had beadbi done of his kesh, dastar, and was publicly humiliated while being brutally beaten.
India is a jungly country with jungly raaj. Law of the jungle. You cannot act like a western gentle man with these savages. You must act like a savage with a savage. That's the only language they understand. A few years ago, my brother was traveling somewhere in Punjab in his jeep. He had a minor traffic related conflict with a Bhaya. This Bhaya went away and came back with two of his friends, now all three of them came back armed with Sothis(long sticks) which they intended to use against my bro. What they didn't know was my bro was also fully armed because he's a tyar bar tyar Singh. So my brother(who is a well built man) steps outside his jeep with his Gandasa. And fearlessly with full beer rass, he challenges them to step forward if they all want to die. Suffice to say, all three of them started pleading.
This video should serve as a wake up call. Join a gym, get well build along with learning how to fight. Read Chandi Di Vaar for that extra martial spirit. If you see a Sikh in distress, don't stand there like a Hijda. Do something to help your fellow Sikh because all Sikhs are brothers. If we don't stand up for each other, no one else will. Attack on one is an attack on all. Never show fear to them. Because they only fight you and beat you up if they think you will not fight back or show fear and act meek.
