I compared the AFD platform to the Republican Party platform and it's like comparing Shakespeare to a third grader's homework.
AFD's platform is 170+ pages, professes an ideology, and has specific policy positions. It talks about drastically restricting immigration, conserving traditional German culture, and pursuing a sovereign foreign policy.
Importantly, AFD specifically says it will fight anti-White racism. This is a promise absent from any conservative party in the Anglosphere as far as I'm aware.
Meanwhile, the GOP's platform is a mere 30 pages, has no ideology, and only vague 'vibes' for policies. You could copy paste most of the Republican positions into the Democrat platform and they'd fit - that's how vague they are.
