I’m simply saying that giving one man absolute power whether it be political

This is standard anti-communist propaganda that unfortunately happens to work on gullible people. It's related to medieval era witch hunting, where you:

1. Create a legend of a supremely evil / nefarious thing, you want to demonize. IE the devil, leaders of revolutionary movements like Robespierre, Stalin, Castro, Mao, Kim Il-Sung, etc.
2. Claim that all people are under the dominion of this sole power, which removes their humanity, and ability to reason or think like you do.
3. Carry out societal-wide demonization and extermination campaigns, to terrorize any potential sympathizers.

Its a really effective tactic that lets you blame a single entity, encourages conformity and intentional ignorance, lets westerners ignore the functioning democracies of socialist states, and the mass movements that supported these various leaders.
