I never tried to imply that it's bad to be vigilant of fascism and right-wing
ideology. I'm very much among the first people who'd step up to prevent an
abomination like the Third Reich to ever happen again. I hold high respect for
people such as Stauffenberg and Dietrich Bonhoeffer, who risked and ultimately
laid down their lives fighting against the Nazis.
The motivation behind the German PC towards Jews and Israel isn't motivated by
that, though. Maybe it originally was, but these days it's but a way to silence
opposition to the questionable politics of the Israeli government. To be fair,
it's slowly fading out, probably not in small part thanks to the emergence of
the internet and new political movements, such as the Pirate Party.
Also, it's not like you can't criticize Israeli politics in Germany. It's
that you will see few politicians who are willing to do it openly, because
it's a minefield.
