It's not a topic in Germany at all. At least not for the majority of citizens and the parties making up at least 90% of parliament seats.
As soon as aggressions between die Linke and SPD fade away, I can easily see this as an realistic way to take.
(I personally think that people should be allowed to act in that way - but the reality is that it made them very easy targets for journalists who wanted to paint a negative impression of the party.)
While this clearly is just anecdotal, it might explain the bigger pattern why the Party had more success 3 years ago while it was clearly economically liberal, and while it is stagnating today where it is clearly turning more and more to the left. Younger Germans, who initially grew the Pirates, neither wished nor need yet another leftist utopia lying to voters about things they cant finance.
