Earlier quoted context omitted.
In the subtitle of the DW link: "One of the suspects was accused of a violent attack on a state politician." Seems like this was not just about posting memes.
The articles are about a handful of cases. You ignored all the others which were non violent and picked the irrelevant detail to share deceitfully as representative of the rest.
Notice also that the poster was only accused, not found liable or convicted. That means almost nothing - you can accuse anyone of anything.
Notice also the guilt by association, where the possibility of the poster committing violence (which isn't impossible) is used to try to invalidate their right to speech.
