IF this very minor incident really happened (a big IF), then it was motivated by the perps' dislike of ISLAM, not the woman's race. Islam isn't a race, despite what Hussein Obama wants us all to believe.
Unfortunately, in the UK, Islam is always handled as a “race”. If you say anything against Islam you’re immediately drowned out as “a racist”. The media bend backwards to defend Islam, supported by the government...too many Muslims have infiltrated their organizations. It’s the same reason behind the new London mayor, Muslims don’t need to be the majority, they just vote as the largest block and stick together.
This person may get a long time in prison for pulling somebody’s scarf. Sad.
