Excerpt:
Londoners have roundly rejected an Islamophobic Twitter campaign in the wake of Sadiq Khan's mayoral victory, responding with messages of unity instead of division.
After Mr Khan became the capital's first Muslim mayor, some people began tweeting vile abuse and comments about "Londonistan" with the hashtag "#Londonhasfallen"
It began trending in the capital but, instead of joining in, the vast majority of Londoners decided to subvert its meaning or simply ridicule the racists.
