I think a representative republic would be fine. Take the US constitution and “enhance” it with a bit more clarity on what the branches of government can and cant do.
I dont really care if I live in a country with “liberal” people. I just dont want them to be able to impose their beliefs on me, through the misinterpretation of the founding documents.
There are no utopias, but we can do MUCH better than what we have today...
