In spite of the view of leftists that 9/11 was just an unimportant outlier that will be forgotten in fifty years, terrorist attacks keep happening. The latest was the attack in Berlin using a truck to ram people, a method that gun control would not have stopped, incidentally.
Now we can ask if this attack was aimed at the right, the center, or the left. Some terrorist attacks, such as any attack on the military, are definitely attacks on the right. Examples include the attack on the Pentagon on 9/11 and the attack on the USS Cole about a year earlier. Others are attacks on the center, such as the attack on the Boston Marathon. It was directed against ordinary people, and there seemed to be nothing about the marathon that was suggestive of either the right or the left. But some attacks are directed against the left, such as the attack on the Orlando gay nightclub or the Charlie Hebdo cartoonists.
My first inclination was to say that an attack on Christmas markets was an attack on the right. However, this essay by a leftist suggests otherwise. The writer talks of Berlin as wonderfully leftist and also rejects the idea that Christmas markets are Christian. So, it’s possible this was an attack on the left rather than the right, or maybe it was an attack on both.
Let me note that if Muslim terrorists were truly bothered by grievances of the sort that leftists impute to them, then they would focus on right-wing targets only and would ignore left-wing targets. After all, conservatives are much more hostile to Muslims than leftists are, plus they are the one who want to wage wars in the Middle East. Why, then, kill some cartoonists or gays at a nightclub when there are so many conservatives in the West one could target?
