I think the culture problem at the root of this isn't Islamic or Arab but primarily a criminal , anti social gang type subculture . First and foremost these bastards are thugs and criminals no matter from where they originated . But the almost identical methods of assault witnessed in Tahrir square makes me suspect it's a particular trait of criminal and anti social gangs from the middle eastern neck of the woods . A calling card of sorts . I honestly don't think Islam has anything much to do with it. To me its just a disturbing aspect of a particular criminal subculture they have over there. That's now making waves in mainland Europe thanks to a massive, barely regulated population influx of literally hundreds of thousands of transient able bodied young men nobody has the first fucking clue about . Many of whom will , naturally, be criminals on the hop or generally out for themselves .
I reckon one good way to nip this in the bud is to make involvement in organised crime..ie criminal gangs..a deportable offence. "You're in a pick pocket , mugging or drug dealing gang ??? Right well , that's not just a misdemeanour . That's organised crime . Fuck off . I'm sure president Assad has a nice punishment battalion on the front line meat grinder he could find a spot for you in. "
Fuck em . It's just organised criminality, nothing to do with Islam or ethnicity . Take these gangs apart methodically and the streets will be a lot safer . As will the asylum shelters because you can bet your ass the same things happening there too .
