It's more like you don't know what the words you are using mean so you keep asserting points that are fundamentally incorrect like Cuba being free or democratic ir having fair elections.
This isn't propaganda. Cuba is authoritarian like China is or Vietnam but unlike how DPRK is because that's not even socialist it's just a hereditary autocratic monarchy.
Source on Cuba letting in elections inspectors? I can't find anything that suggests this and only sources that say the opposite. If it helps I can read Spanish.
Source for them not letting in inspectors:
