Are British Asians more aggressive against racism compared to American/Canadian Asians?

Because it seems to me that South Asians in the UK are a lot more outspoken. Perhaps this is due to the history of British Asians going back decades to the 70s/80s and the militant youth movements; but Asians here fight back hard. When the race riots happened in the UK, you literally saw gangs of Asian youth carrying machetes and patrolling the streets.

When the EDL went to Whitechapel a decade ago, they had rocks thrown at their coach and were driven out by the Bengalis.

Curious to everybody’s thoughts.
