The AfD literally has meetings about mass deportations and many members at the top are literally neo-nazis. One member of parliament was even involved in a group that was planning a coup. When they started defending the Waffen-SS instead of discussing real problems it was even too much for Rassemblement National. You talking points about fake news are following the party line to denounce existing institutions and to appeal to conservatives.

There is no way one can describe the AfD as center-right. This is obvious fact that emerges from any amount observation of post-WW2 politics in that country, and how the AfD compares to standard center-right parties like the CDU/CDS and the FDP.

Complaints about fake news and what the mainstream media supposedly says about anything are usually, in themselves, fake news.
