> The article never made this point. All it said is that they kill more people.
If that was the case they would not have mentioned terrorism. The comparison to terrorism exists because it makes the article travel better between members of the Blue Tribe who think anxieties over terrorism are overblown and better gun control would be good.
Remove the link to terrorism and the article would have had less currency within this group.
> I always thought terrorism was feared because this is an emotion which the government and the media sell.
The message already resonates with conservatives as they already have high anxiety about losing their 'way of life'. It's not just a case of a message that has been sold by the government and the media. Real people's innate fears [0].
> I really don't think any such worry is realistic, these people are marginalized and completely inconsequential to their nations GDP or the progress of civilization.
Yes - in many cases. But there are a few countries in Europe that will be majority islamic over the next 100 years, and in those places people might lose their 'way of life'. Demographic changes are underway.
As you probably realise, fear isn't always rational. Many groups of people are very sensitive to fears of losing their 'way of life'. Even without the existence of a significant threat.
