The comment you're being a douche to declares they only can read the title. The title makes two statement of facts formatted to imply that one cause the other. The comment you are being a douche to givers their opinion that correlation does not mean causation. The topic of the title and article is one that is widely discussed in all cultures and regions.
Do you really think being a douche was the appropriate response to this scenario? Did the person make preposterous claims under some false front of reading the article when they actually didn't? You post an article protected behind paywall, then act like a douche when someone comments? They clearly were interested in reading what you took the time to post so explain why your response is so abrassive? I admit I'm way over the top in my reply to you about your response but fuck that was such an annoying way to act.
Maybe you shouldn't expect everyone to either subscribe to the Wall Street Journal or understand how to bypass paywalls if you want something to be discussed.
European countries opened their doors to immigrants not for altruism but to flood the labor market and devalue labor to generate more profit for European oligarchs
