Why on Earth would I need an argument?

Just because only arguments is the basis of any sane conversation. :)

It's well known that any serious opposition to Putin gets murdered or imprisoned.

Do you understand that most serious opposition to Putin is not some West paid liberals, but Communist Party of Russian Federation (conservative-right) and Liberal-Democratic Party of Russia (far-right)? With real support among population, not some Western MSM fairy tales. That is serious Russian opposition, not some Western elites dick suckers.

The question is rather why you go to so much lengths pretending that this election wasn't rigged from the start.

This time there was no any need to rig elections at all. As I already said it was protest voting - people willingly voted for the dude most hated on the West.

You have to be fucking retarded to assume that average Russian sheeple will beg for installing some Western shill because West denied to sell him Mercedes. It is exactly opposite. "We will not sell you Mercedes, orc, until you will bent before us!" - Russian sheeple answer will be - "So fuck you, fuck all your relatives and ass partners, fuck your inbreed pedo elites and fuck all your wishes". And he will willingly and consciously vote for Putin if he will see that this inbreed Western dumbfucks hate him. Along with ordering Mercedes through Kazakhstan or Georgia, not giving a single fuck to some stupid Western dreams about "isolation". It will become his point of honour - to do what Western elites didn't want him to do - vote for Putin and fuck Western "laws" and bans.

You do not understand anything about Russia at all.

Meanwhile, you told me nothing about King Charles f.e. Who voted for this Britain ruler in your "freedom and democracy" world? Where is his opponents in the fight for taking King position in Britain?

Somehow it is OK for "free and democratic West" to have rulers who wasn't elected at all and rule till death unquestionaby, but for some unimaginable reason for the same time you are very worried about elections in Russia.

Well, I could tell you only one thing about that all - elections in Russia is not your fucking business. Go fuck youself, or cry in a corner about some western dicksucker fate in Russia, or try to elect another King of Britain, whatever. Nobody cares.
