The wording includes an important caveat:

(4) Gegen jeden, der es unternimmt, diese Ordnung zu beseitigen, haben alle Deutschen das Recht zum Widerstand, wenn andere Abhilfe nicht möglich ist.

This roughly translates to

Every German has the right to resist those who seek to abolish this [free and democratic] order if no other means are sufficient.

The conservative politicians/judges have watered it down to the point where you can only violently resist them once democracy has already failed.
