You just replicated the most popular excuse apologists of Islamist terrorism use to give, only from the "other side".
(Besides it's inaccurate - the articles say an argument about leashing dogs escalated into racist abuse and the stabbing attack.)
That's the whole point. A small sector of Muslims will blame the fact that the other side did things against the views of their religion as a reason to kill a teacher and that causes tensions within a multi racial community. It becomes a war inbetween a community. Look at this news article -
"Two Muslim women were 'stabbed repeatedly' under the Eiffel Tower
amid rising tensions in Paris after the beheading of a teacher last week.
French police have arrested two female suspects after an
argument about dogs allegedly descended into violence and racist insults including the words '
Dirty Arabs'."
The rising tension happened because of the splitting of a community that happened due to one community thinking 'a drawing of their prophets shouldn't happen and now is suitable for murder'.
Who ever dies, whatever their names, personality or religion is - the fact they died is awful.
If this random woman had killed two random women just about their dogs then that's one thing hardly related to a religion or a colour of a person's skin.
But we see rising tensions between 2 communities happen after the blowing up of an arianda grande concert, the blowing up of underground trains, the blowing up of buildings and planes like 9/11, the killing of a teacher. Why? Because the religion and racial views are bought in as a reason for some people in a community to act in a certain violent way. Then what happens is the other community may retaliate with their own religious or racial views aswell.
If someone from a non atheist, Christian, Muslim, Hindu, Buddhist, catholic, Jewish religion kill a random person in a multiracial community over something random that happens regularly like the thieving of money or even sexual abuse - does the persons religion ever get highlighted as a cause? Not really for me, the killer didnt bring a religious or racial view as a cause of their actions. Then compare that to people who kill someone for a drawing of their religion or shout their gods name before blowing up a population in a concert or underground train - it leads to tension directly against that religion and race because they themselves bought it up.
