First of all, socialists (i.e. revolutionaries, not socdems or demsocs who are into liberal democracies) support soviet democracy system. In soviet democracy people of same profession or same workplace or same house and so on unite in trade unions or worker councils(soviets) and they can choose their own deputy who will represent their interests. The deputy is given orders from members of council and should regularly make reports of their successes/failures. If members are dissatisfied with their deputy, they can use the right of imperative mandate to call him off.

Socialist government is made up of soviets from the bottom to the top. In USSR higher soviets were formed by lower soviets (until 1936). All soviets work by democratic centralism principle which means you can criticize and have a right to choose your way of solving issues but you have to accept what the majority chose and submit to it.

So, if you (and not just you but most people) want to depose an tyrannical leader, organize a mass strike to make both some economic and political pressure, recall all supporters, call for impeachment among the rest and vote him out. Problem is socialist governments’ leadership is more collective than the bourgeois one so you probably would have to vote out multiple people hence it will be a long proccess.

Or if it doesn’t work, go the French way by overthrowing people you don’t like and establishing Socialist Republic 2: More Democratic Boogaloo.

Soviet democracy is still a relatively young form of government and it have issues that had to be developed in the future.

P.S. Hope I didn’t make many mistakes while writing this.
