The Speech That Got Me Banned from Germany

Hm.

Googling in German now suggests that what happened is: Someone else did get such a ban (called "betätigungsverbot" in German, which means "a ban on putting into action") and the police broke up the meeting in which Varoufakis and the other guy were to speak. Speakers who hadn't entered the country yet on the morning of that day were turned away at the border, without any reason given. Unsure how many that was.

The other guy seems to be… not very nice.

Varoufakis' speech was certainly not the reason for the other guy's Betätigungsverbot.

very good researcher

I hope he stays researcher and write more books
