[Marvel, DC] Does anyone ever bring up how some of the royal Avengers and Leaguers are dictators?

Wise, prudent and fair dictators but dictators nonetheless. There's a reason why so few modern countries are monarchies.Atlantis and Asgard are explicitly NOT democratic; does anyone ever mention it to Aquaman and/or Thor?

I mean, Namor definitly makes sure that anyone in a room knows that he is King as soon as he enters it. There is also a reason why Namor swings from hero to villain every so often, he does whats best for his people, not for everyone. He is also kind of an asshole. 

Thor is a god, and gods follows their own rules. Asgard has tried to be more democraftly lately, with the congress of worlds under Freias rule, but Odin did not agree with it, most likely because he has ruled asgard for the last 65 million years or so. 

As for Black Panther, who usually isnt a an avenger but works with them, he also usually makes it very clear that he is a king, and he can do what he wishes. 

So no, there isnt really any need for other avengers members to point out that there are dictators on the team, becasue they will be the first one to tell you about it. And then they will not ask your opinion on the matter. If you were to mention it, they will give you some wisdom about how a country with a king will be more effective in times of crisis, and then they will point out that, being an avenger, you are constantly in a time of crisis. Or thor will say "we are not mortal men" and leave it at that.
