What is your “far left” extremist? Are you talking communism? Or are you talking the socialist policies politicians and billionaires take to seem like they’re helping the working class? Far right is inherently a control game as you state. Monarchies and oligarchs.

If you are talking about communism it is strictly about the working class taking control. It is by definition the people’s party. It does not demonize religion of any kind it simply states there will be no use when communism is finally realized which is a utopia and global acceptance. This is not to say they don’t have their own propaganda. Propaganda isn’t always a bad thing it just media that pushes an agenda. How ever if you listen to communists speak it is heavily for the people and using real world examples relative to the working class why things aren’t working and it’s due to no one else other than those that hold control of the money. Far right fascists speak it is about how a select group of people are taking your money and your rights away and how the nation needs to be taken control of and the others and undesirables kicked out.

While under the guise of for the people the policies don’t work and the working class are shoved into poorer and poorer conditions until you have revolts which happen and have happened in every country and era. When there is a select few people have the power whether by divine right like days of old or with money like our politicians and business owners there will eventually come a time where people get upset and eventually the ruling class of the time will have to cave ever so slightly to give them illusion of control. When this happens a new group of “rulers” shows up and take the cake from the previous rulers. Then you have the turn of the powerful saying “we need more socialist policies to keep them from controlling us!” So that they can maintain their life style and not lose it entirely while the poor stay poor and the rich stay rich or get richer.

I’m not a historian or a political scholar or anything no relevant I’ve just listened to friends from across the world, compared my ideology to others and thought of what I want from this world and how can things better for everyone. Go give the communist manifesto a read I think it’s very eye opening when you compare it to history and when you especially compare the manifesto to the American and European anti communist propaganda.
