The statistical chances of someone dying to a terrorist attack in the western world are ridiculously small. The reason why people get up in arms is a combination of how rare they are and how violent they normally are. There is no level of hysteria that is appropriate for them. Hell, you're more likely to day any given day to getting hit by a car than a terrorist attack but you aren't all hysterical that cars are allowed to be driven.
You are comparing accidents to planned mass murders.
It's not about the number of deaths that worries people.
It's about the idea and the type of danger.
We've been living in a world where, apart from accidents, the most a regular person would have to endure would be maybe being in a bank while robbers come in. And even then the aim for the robbers is not to kill anyone.
These terrorism examples, however, bring out the idea that there are groups of people who don't quite care who they will kill as long as they kill as many as they can. And it doesn't need to be a bank. It doesn't need to be a factory. It doesn't need to be a school. It doesn't need to be a church. Any place where there are people is a potential place for them to do it.
And they are actively encouraging others to join them. They engourage each other from other side of the world to the other side of the world.
Now, let's talk about car accidents.
I knew a guy who died when a car crashed him. It was an accident. It didn't make me fear for cars or people who drive them. At most it made me a bit more aware while walking around. Now, let's say there was a lunatic whose sole purpose was to crash and kill. That would've made me certainly more aware of my surroundings but maybe not scared if I thought it was just one crazy person being crazy. Now imagine there would be groups of people who were encouraging others to crash their cars at poeple. It makes the situation completely different.
Even if the amounts of deaths wouldn't get much higher and even if it wouldn't make statistically much more likely to die in a car crash, I definitely would have my right to be worried about the current situation.
You are also ignoring that it probably is way tougher for people to cope with a friend or a relative dying because a madman decided to bomb people or stab them on the streets than it's to cope with a friend or a relaive dying in an accident. Accidents at least don't happen because someone did something out of hate. In accidents there normally isn't any ill will pointed towards anyone.
So it's not just about how many dies when it profoundly affects also those people who knew people who died and those people who were in danger of dying.
It's not just the dead or injured who are victims there. Victims are also those who have to witness such tragedy.
Incidents of terrorism are so rare in western countries that they are swallowed up entirely by the wider crime statistics. Comparing number of incidents is utterly pointless and nothing more than ridiculous headline grabbing and scaremongering.
The number of terrorist incidents should be zero in western countries.
One is too much. There is something very wrong when we start to think we should expect yearly terrorist attacks.
Regural crime is enough already. We don't need groups of people who just want to kill another groups of people. We have already desensitized towards regular crimes. We accept regular crimes happen. We even accept people die during thes crimes.
In Finland we already have have our own crazy people doing crazy things. One woman killed herself and her children because she was angry at her spouse so she decided to ram her car against the bus the spouse was travelling in. We've had a couple of school shootings. We've had someone randomly attack others with a knife. One guy stabbed a young girl to death. Another stabbed a random homeless person to death.
We don't need to expect groups of people who are dedicated in planning mass killings to make their yearly massacres. We have enough other things here already. Thankfully we are not yet expecting attacks in Finland. But then again France, Germany, the UK and even Sweden weren't forced to expect that this frequently either a few years ago but here we are.
