It's fair that you disagree with AFD, even disagree a lot. But could we please rethink the use of "far", when they have 20% of the seats in parliament?
Their views, are the views of 1/5 people you'll meet in Germany, on average. If we mirrored this logic, the SPD should be "far-left", Grüne should be "far-left pro" and Links should be "ultra far-left pro max".
This use of language waters out the meaning. Just like calling everyone commies and nazis... also I think it'll have the opposite effect you hope.
As we all know, any popular political party in Germany can never turn out to be literal facists
Well they are definitely far right especially if you compare them to other right wing parties in Europe. AfD is monitored by Germany’s Federal Office for the Protection of the Constitution and their former youth organizations have been designated as confirmed right-wing extremist by them. They talk about mass deportations of citizens termed as "remigration" and leading party figures intentionally used the banned Nazi SA paramilitary slogan "Alles für Deutschland" ("Everything for Germany") at campaign events.
In 1933, NSDAP gained about 44% of seats which would make them more centrist than AfD by your logic.
