Not exactly an ideology though.
and potential incidental dangers from unrest in confined spaces.
It is not that I have a singular focus on one religion nor one political movement, so much as that the evidence suggests that, currently, some movements have more violent offshoots and a more violent profile. There are a handful of political and religious ideologies in the world that lead to more suicide bombings and hijackings per year than, say, the total number done by believers in Zoroastrianism, Sikhs, Confucians, Hindus, Yazidis, Jews, Buddhists, Libertarians, Democratic Socialists, Freemasons and Christians combined.
If you had, for instance, Jim Jones's cult or the Aum Shinrikyo boarding airplanes and blowing them up on a regular basis, and your response was that a person had to be a single-minded bigot to notice the fact that most airplane bombings originated with this particular ideology, then I'd say you were ignoring facts or willfully making excuses for ideologies which brainwashed people into doing those things. Possibly for reasons related to disliking your own society, which is perfectly fair, but certainly not neutral or scientific.
Notably in India, there have been a few times where Sikhs have been at the head of violent revolts - and a few times where they have been targeted by violent purges/genocides.
They’re generally pretty chill, but they aren’t pacifists.
Anyway, I wasn't trying to say that Sikhs are more or less likely than any other group to be pacifist. I was saying we shouldn't even be having this discussion, and simply scan people for weapons, and use things like actual random screening to help as needed. And that religious reasons for carrying weapons are not a valid excuse.
[edit] To be more specific: An individual with an extreme belief about anything is as dangerous as an extremist member of a group with extreme beliefs. So the smart thing is to look at the beliefs and extramicy of each person. If you find someone trying to board an aircraft who doesn't care if they make it to the end of their flight, that is a security problem.
In contrast, trying to interview and run background checks on every person boarding a plane to figure out if they are an extremist on a mission or not is (a) much more invasive, and (b) much less likely to work out. Especially when you actually don't want to prevent fundamentalists from flying on planes (I don't think preventing some major evangelical church leader or some radical rabbi from flying would even be constitutional, and clearly not a popular move if attempted).
Note that I am not at all advocating for extra security targeting of Sikhs or any other such religious or ethnic targeting. I am just saying that no one should be allowed to carry a weapon on board a commercial airplane, for any reason.
> The bombing of Air India Flight 182 is the worst terrorist attack in Canadian history and was the world's deadliest act of aviation terrorism until the September 11 attacks in 2001. It remains the deadliest aviation incident in the history of Air India, and the deadliest no-survivor hull loss of a single Boeing 747
