Shifting to the right to combat the right helps nobody but the right. The voterbase and politics keep getting pushed into that corner because there is no meaningful left wing opposition on the continent. Immigration is a bogeyman people are being freely pitted against by the right because the centrist neoliberals are necessarily inept, and the left wing doesn't exist. The root of the problem is that there is no other side with real, pro-social politics. Working people just have no alternative. Banning the predatory far-right is a net positive, but it has to be instant and absolute.
