@saab,
Osso could be forgiven for believing you were. Hate and bigotry are not confined to Muslims. Prior to this outrage Manchester was bombed by Christian IRA terrorists who also targeted innocents and killed children. Christian White supremacists in America have also butchered plenty of innocents. Closer to home there's Anders Breivik.
The vast majority of Muslims have condemned this atrocity. Muslim groups in Manchester have been at the front in trying to help the victims, from Muslim taxi drivers who took people home for free on the night of the bombings to Muslim, Libyan women brining pastries to hospitals for the victims and medical staff.
Manchester will not be divided, but you do sound like you're claiming some sort of moral superiority for Christians. That's what the extremists want, and that's how division starts.
