I’m not sure what to say. We can talk about the exact meaning of the words, but it doesn’t really matter.
I’m not saying AfD is good or bad, just telling you the facts. AfD surpassed CDU (not the union!) in the latest polls. In the last elections they “won” in east Germany. You can’t block a party, if half the country votes for it. Let’s see what’s coming.
I'm not even disagreeing, just right now the AfD does not have actual power yet. They cannot make federal laws or decide policy.
They probably will be able to do that either after the next election or after the government coalition collapses.
But as of now all they can do is b*tch and moan.
Btw, who says you can't block a party just because half the country voted for them? You can't wish the sentiment away, yes, but you can totally force them to rebuild the party infrastructure. Again and again, if needed, if they keep making an illegal extremist party.
