On the other hand, in modern European politics very often anything that is traditional right wing is labeled "far right extremists" anyway at this point, especially if they are a bit too critical of the EU and open borders. The only thing 'acceptable' is "centre right".

For instance in France, at this point, the National Rally (Le Pen) is not really more in the right than the traditional conservative/right wing party was in the 70s and 80s (with years in government). It is plainly just "the right" and largest party in Parliament, yet they are labeled dangerous far right extremists because it is (less and less) helpful politically...

Not sure exactly how the political positioning is in Germany but overall "far right" and "right-wing extremists" have lost all meaning generally in Europe because those terms are so abused. The current German government coalition does not seem to particularly reflect the democratic result of the latest election (majority on the right), same as in France.

So it makes sense then: there are two parties. The center is the imaginary line in the middle. One of the parties is center-left, the other is center-right. Logic! :)
