It's a strange mix of very good tech talks and left-wing extremism. I'm looking forward to watching "Who cares about the Baltic Jammer?" and "The art of text (rendering)" as examples of the former. An example of the latter is "selbstverständlich antifaschistisch!"
That last polarisation and othering is odd, unnecessary, divisive and not generally representative of 39c3 talks nor the CCC.
Antifascism is a long tradition among humanists and European hackers and not related to "left-wing extremism".
Why do you find it necessary to discredit the message of that talk? What's the supposedly extremist message in there?
