Football ultras saying very nasty things and beating up eachother is usual in Europe. Local Arabs joining in when the opposing team is from Israel shouldn't come as surprise. But on social media one group of Americans started talking about Jews being "pogromed" by Muslims and another group of Americans started celebrating that Israelis were getting beat up. American social media is a threat against the social fabric of Europe.
