I can't believe you're still insisting on this complete straw man. AfD's stated position on immigration is very easy to look up and it's NOT this. At all. You are parroting a leftwing lie.
They want to deport undocumented migrants and remigrate certain refugee groups, such as Ukrainians. You're free to disagree with that position, but lying about it and then descending into such an absurdly histrionic spiral over the matter does your argument absolutely no favors. That only supports what people like Caldwell are saying and, ironically, precisely bolsters AfD's argument about suppression of the discourse and an honest discussion of Germany's problems.
In fact, you've offered a perfect demonstration of what Caldwell covered in the first section of this very essay.
> you clearly don't know the history
Are you seriously trying to imply I'm not aware of the Holocaust?
