I don’t care what their circumstances are, fuck sympathising with people training to commit mass murder, plenty grow up in those conditions and don’t turn out to be terrorist dogs.
But there’s a reason why that number is higher in certain environments than others, just like more people get attacked by sharks at the beach than they do at home. Plenty of people who visit the beach don’t get mauled by aqueous carnivores.
Sympathizing doesn’t mean advocating for or excusing their actions, but pretending that terrorists are some “other” group to assuage your conscience doesn’t help anyone. These are PEOPLE and people are driven by the circumstances they find themselves in. Until those circumstances improve, people are going to keep dying.
