dont know much about western countries besides the usa, but here, most of the terrorist attacks are commited by christians.

In the US? 9/11, San Bernadino, Orlando gay club, Fort Lauderdale, etc. seem to be difficult to top by "christian terrorists".

Globally Islam is the terror force par excellence, no second terror source even comes close.

Are you saying yoru from U.S.?

What terrorist attacksa re commited by Christians?

You do realize that to be considered "by christians" that is has to be in the name of christianity. A school shooter or unibomber who happens to be of a certain faith does not mean it's in teh name fo that faith. Most terrorist attacks done by muslims are predicated by "allah Ackbar" or something of the order that shows they are doing it for a religious reason.

If I shoot up my work tomorrow, my work place violence is 100% non religion related.

Thinking on major events, I can only think of a few recently that were non muslim related. Sandy Hook shooting (some mentally unstable white person, no idea motive). Planned Parenthood shooting (very well christian terrorism, guessing he was motivated by somethign like religion), Church shooting (that white kid shooting black people at church. That was purely racism, not religious)

Otherwise on other spectrum we have Ohio, guy drives car into peple and starts stabbing (muslim terrorist), we have a bombing in New York City (didn't really follow, so no idea who this was) we have stabbing in st. cloud mall (muslim terrorist) we have the sniper at Dallas during meeting (muslim terrorist) we have night club in florida (muslim terrorist) we have san bernardino work shooting (muslim terrorist) we have boston Marathon (mustlim terrorist)

That's all I can think of on top of head. But fairly certain I grabbed the Major ones. You know with high body counts/injuries in recent years.

Exactly. And those cases of terrorism in the middle east? I can guarentee 99% of them are committed by muslims. So saying most attacks are by christans are rediculous.

Yep, but again it comes down to MOTIVE anyway.

Take this very event. It is similar to the one in U.S. where we had a white (guessing christian) shoot up a church. Both are people shooting up peopel in a place of prayer that they themselves practice.

The U.S. guy was doing is to shoot up blacks, thus not a Christian terroristic attack, but a racists terroristic attack.  

This Canadian guy was doing it for his faith, thus a muslim terroristic attack.

Was the Canadian person muslim?

He actually seems to be a very anti-Muslim French Canadian who may have for some reason shouted, "Allahu akbar!"

I never understood the necessity to distinguish between terrorism and plain murder/shootings. The effect on the involved is the same, regardless of motivation. If anything, by making the distinction and giving further attention to terrorist attacks, by definition of terrorism, you are helping their purpose, spreading fear.

Iregardless, terrorism is an insignificant problem in the United States, or in all wester countries, really. Since the September 11th attacks, only approximately 200 people were killed in further acts. In the same time frame, over 250 000 homicides were committed and 500 000 people died of car crashes in the US. It's ridiculous just how much media attention these occurences get, especially considering that they were done FOR the media attention.

No. He asked people on the internet when Muslims usually go to the mosque (for an alleged anti-muslim demonstration) to plan his attack.

I'd say no. A racist, no question, but Quebec as a whole is extremely unreligious (often anti-religious. This has some interesting historic reasons.), so it's not honest to say that he did it in the name of christianity without having any background information.
