They crossed a very serious line by doing what they did in a church. This made them, without their realizing it probably, the sharp tip of the sword against Christians that is scandalizing the world.
The fact that we don’t like Putin and his treatment of dissidents is almost irrelevant here, except that it has confused the issue enormously.
Does anyone remember the “abomination of desolation standing where it ought not”?
And once again, that church is now headed by an ex-KGB associate of Putin's and is now a cheerleader for Putin's fascism.
I would think that desecrates the church far worse than anything Pussy Riot could dream up.
