> Limiting free speech
This accusation is very vague and it could mean anything. It's surely more limited than, say, in Sweden. It way less limited than in Saudi Arabia.
> banning political opposition
Russian parliament consists of 4 parties, 3 of those are oppositional. I'm sure there is a number of banned NGOs, but totalitarian countries usually don't have this kind of political plurality.
> arresting dissidents
Notice they don't arrest people for being a political dissident? Khodorkovsky was brought up on tax evasion charges (which he undoubtedly committed). Pussy Riot was charged with hooliganism (which they undoubtedly committed). Were the trials politically motivated? Sure! Is it unique to totalitarian states that people who oppose the establishment come under higher scrutiny? Please...
> persecuting people for their sexuality
Now we are venturing into the cool-aid area. Modern Russia never prosecuted anyone for their sexuality. Homosexuality means attraction to the same sex and people are free to act on their attraction in Russia. There are a number of openly gay public figures. Russia has laws protecting LGBT minorities from discrimination. I would venture further - Russian government's policy right now is as progressive on LGBT rights as possible in Russia. The populace is hugely homophobic, ranging from 'being gay is a disease' to 'gay must be stoned'. It's the same in most of the former Soviet republics - even in the Lithuania over 80% of people consider homosexuality a perversion [1].
And by misrepresenting the fact about the state of the LGBT community in Russia the Western media only make Putin's life easier, since he can present it as a 'them-versus-us' issue internally. Compare [2]
> invading neighbour sovereign states
Is the emphasis here on 'neighbour'? Because if invading other countries is a sign of totalitarianism than the list of totalitarian countries will have some very surprising names on it.
> I don't know about you, but I think "totalitarian" draw a more correct picture
Which is your good right. I just don't see enough facts to support your opinion that Russia is a ' state [which] holds total authority over the society and seeks to control all aspects of public and private life wherever possible.' [3]
