IMO, canceling the Russian shows in 2013 was a major fault.
It's a question of loyalty towards the fans who had paid their tickets (and arranged plane tickets, booked hotels, planned days off or vacations...) and were looking forward to that moment.
At no point Mark or whoever in the band was threatened by homophobia or human rights question.
The only ones who paid the price are fans like foma. 20 Thousands of fans paid for a caprice.
What about Putin ? Since MK is not a judo champion or an ice skating beauty, Putin probably doesn't know who he is !
