At least in the parliamentary system, you are voting for an abstract notion of how things should be run, a worldview, or a list of policies.

In the American system, the cult of personality rules above all. The vast majority of Americans disagree with what Donald Trump is implementing right now. That’s clear when you ask people in the abstract. But we don’t choose that way. Personality and celebrity rules the day here.

Parliamentary systems with proportional party list voting systems are far from immune the cult of personality. See: Hitler.

There's a reason why so many governments with such systems one would consider "free" still have to outright ban parties from elections.
