Also the US following UK's FPTP system inevitably creates a 2-party system, you simply cannot have just 2 parties representing all of the political spectrum and needs of a nation of 340 million people, and very diverse people at it, across a vast swath of land.

Even though most Continental Europe elections end up being a race between 2 major coalitions at least there's fluidity in the composition of these coalitions, sometimes the right-wing coalition embraces the centrist parties, or the greens, sometimes it's the left-wing coalition, this fluidity creates a lot more of nuance and compromise in politics rather than choosing Team Blue vs Team Red. FPTP is a dumb election system.
