He's not directly comparing our Government with the worst of what Russia does and he's not insulting anyone who's suffered at their hands. I think his point is that it's a bit rich to judge people for not protesting when they could get imprisoned for 10 years or worse, when we allow our Government to screw us over consistently without a peep, and we don't have those fears over us (although they're actually trying to clamp down on our rights to protest via the police, crime, sentencing and courts bill)
