> US President has called Zelensky a dictator (and for good reason, Poroshenko, the previous Ukrainian president, has basically said the same thing a few days ago)
You can't be serious that you consider that to be a good enough reasoning.
Zelensky's support / approval rating is well over 50% (according to polls). Zelensky defeated Poroshenko, getting 73% of the vote in the 2019 election.
> Zelensky defeated Poroshenko
And yet he still felt the need to start politically repressing Poroshenko with sanctions and branding him a traitor, that's the mark of having a dictator in command of things.
