The issue is arguably most vivid in Germany, where calls for a ban of the far-right Alternative for Germany (AfD) — the country’s second-most-popular political party—are growing and the government wants to cut off funding sources of right-wing extremist networks. In Britain, the government wants to keep extremists from meeting with lawmakers or receiving public funds, and it plans to publish a new list of groups it considers “extremist,” focusing more on beliefs rather than a propensity for violence.
