'The effort of Rep. Slotkin is commendable. Designations, underused in the European context, should help with countering the threat of violence from extreme right-wing organizations,' Rekawek told BuzzFeed News. 'However, this must be informed by a thorough analysis of the local far-right scenes which include a plethora of actors who often talk the talk, but do not walk the walk as far as violence is concerned.'"
