This is a very obviously biased argument that both sides make about themselves.

The AfD literally published a manifesto of new and notably more conservative policy goals in 2017.

They do not claim to have the political stance of Germany 25 years ago, they themselves say that they are something new (For example, point 1 is an adoption of Swiss-style direct democracy, which is a notable shift to the right).

I encourage you to think much more deeply than "I saw this meme and it resonated with me," because the same is true of the American Tight, despite Elon's claim (Regan, for example, was very famously against Tariffing Canada).
