I would say the older generation tend to afraid of yobs, and that makes a lot of sense.
There is a distinct lack of respect for older people in British society. I know I'm talking sterotypes here, but you see elsewhere where it is actually a "macho" thing to help old ladies cross the street. Here, that is not the macho thing, caring for the elderly is done by machines, by paid help or not at all. How we treat the elderly in this country is a great crime.
So the older generation probably do hate the younger generation in a way. Not their specific grand children, but the general youth, who is loud and disrespectful, and sometimes abusive and scary.
