Definitely we need to get rid of First Past the Post, but while our parties are polarized, they are both far to the right of the vast majority of voters.
> What if I like guns but I want universal healthcare?
That is actually fairly common. Gun control can be done in a nuanced way, and we can have more guns with few instances of gun violence esque Switzerland if we train our populace to properly secure and disarm their guns when not being actively used.
Comparatively, people like my great grandfather thought it was fine to leave a dozen or more loaded guns of varying types all throughout the house. Not great when a shotgun falls out from behind the stove and nearly gets ya.
> What if I want a smaller government but I also want great environmental policies?
Hard to do, small gov't = small town corruption if you look at areas that take this approach.
> The US system was ok in the 18th century but now it's a relic. Some things don't age well.
Definitely, we need to update our antiquated political system.
