Also, to add to this: Leftist ideologies does not have to be authoritarian or have to involve genocides like some regimes have did some in the past. Leftist ideologies is compatible with democracy, and some might argue that Leftist ideologies require a democratic system.

Example: North Korea currently is called “Democratic People’s Republic of Korea” but I doubt most people would actually consider that democratic.

Now imagine someone just started shouting “Democracy is bad because North Korea is a Democracy. This is why Monarchy is better!”

See how idiotic that sounds. Same thing with claiming all Leftist ideologies are bad because of a few failed “Marxist-Leninist” societal experiments. Some socialist policies have been successfully implemented. In Norway, although it’s still a capitalist country, has implemented some socialist policies under the “Nordic Model”. This is sometimes referred to as Social Democracy. See how democracy still exists in Norway?
