Yes those things are terrible, but what is government going to do about this problem? That's Facebook's problem to solve, not the government's. There's still tons of racist/dumb people in our country, you can't legislate ignorant people to stop being ignorant.
So if Canadians are going onto Facebook in record numbers to foment hostility against their fellow Canadians it's a "Facebook problem" ?
The government should at least make a statement for unity. That's the minimum they could and did do.
The only thing to cure religious ignorance is exposure. People literally need to meet and interact with Muslims to understand that most of them are regular people like you and I, and aren't crazy or violent etc. People fear what they don't understand.
People need to call out others for being racists and xenophobes and saying this is wrong.
