I'm curious too, how they justify the bad things the Empire did, It kind of bothers me to think there just that evil, or that blind to the things the Empire did.

In Episode II, Anakin summarizes this quite well. He wants a galaxy where people reach an agreement over what will be the best for everyone. But he adds, if they don't agree, "someone wise" should force them to do so. In other words: we need someone wise who knows what's the best for everyone and this person should have the power to force everyone else to comply with this person's decisions. And if this is dictatorship, "well, if it works..."

Yes, democracy is messy, because it's a system where decisions are made based on agreement, and no one can force others to agree with him. It requires genuine consensus and voluntary, genuine, freely formed cooperation. Which puts responsibility to every single individual. But this is the best we can get. When people cease to believe in cooperation, they don't want its messy parts, they trade it for compliance: they want a powerful, benevolent leader who will solve their issues, who will think for them and tell them what to do. They want their world to be good, but also simple.

And tyranny is supported by many people who believe, they know what's best for everyone, and those who oppose them, are unable to recognize this, or just simply "evil,"

and it might take brutal measures to broke down the resistance of the fools and the vile, but it's for the greater good.

I agree that Democracy can be very messy, it would work a lot better if everyone could just agree with each other. I don’t really support Dictatorships, but a lot less chaos can technically occur from them. This is an aspect of Anakin and Padme’s relationship that I really like, even though they have different political beliefs they were still able to love each other, and she was a politician herself. I really wish that people in the US would understand that you don’t have to see eye to eye politically to love each other.

Well, dictatorships achieves "less chaos" by imposing a system of organized suffering. So, that's never a justifiable response to chaos!

As for Anakin and Padmé, they both laughed his comments off, so that wasn't really like "you might support tyranny and I might support democracy, but I still attracted to you, so let's get married." When Anakin got serious about this in Episode III, Padmé made it clear that she can't follow Anakin down on that path.

The important thing to note is that Padmé loved Anakin still at the end of Episode III because she didn't reduce Anakin to his current state of mind. She was aware of the fact that the qualities she appreciated in him, that she found attractive and enjoyable, the good person she fell in love with, is still there, just submerged under his dark parts. And that was possible, because Padmé's love for him was based on "I love you, thus, I want you to be happy and not to suffer" not on "I love you, so supply me with happiness." This is the difference between compassion and attachment, caring and craving.

What the world (not just the US) needs is to acknowledge and understand that we're the same human being in wanting to be happy and not wanting suffering, and all we do is motivated by that. This brings forth our genuine wish for others to be happy and not to suffer, which is love, the kind of love that's endures not seeing eye to eye politically/religiously/social ideologically/morally etc. This is the basis of functional democracy.
