Putin's faults do not cancel out those of his opponents.
The totally unreconstructed Communist Party of the Russian Federation, notable for its Soviet flags at demonstrations.
Those who on those occasions wave the equally ubiquitous black, yellow and white of Russian ultranationalism in all its anti-modern, anti-urban, anti-scientific and anti-Semitic awfulness.
The Caucasian Islamists.
The National Bolsheviks, whose flag is that of Nazi Germany, but with a black hammer and sickle in place of the swastika.
Pussy Bloody Riot.
And now, a Western neocon stooge for whom next to nobody in his own country voted.
In fact, it is difficult to see why anyone in Russia would have considered Boris Nemtsov important enough to kill. Except to get a reaction in the West.
