The professor is a typical brainless libtard who has already bowed down to Islam and demands the same from others. There are more idiots of that kind, but nevertheless, they won't reach their aim that easily. At least not now, but who knows what will be in 10 years or so, if nobody stops the madness.
It's high time for a U-turn. But unfortunately, too many gullible sheeple still don't see the threat. They are more busy to fight the "evil right-wing enemy" (or in other words, everyone who isn't left-wing). I don't have much hope that the situation will change soon. If we're unlucky, things will even get worse after the next election, since Merkel's liberal opponent Schulz from the SPD party is already waiting for the starting shot to continue the devil's work that Merkel has begun in his own, even more aggressive way.
