I don't think this is entirely true, it's more that there are areas where the US would be viewed as more left-wing on average than Europe and areas where it's more right-wing. For instance, the US has legal gay marriage when it's still banned in some European countries and legal marijuana when it's only decriminalised in most of Europe. DEI is also bigger in the US, and so are ideas like defunding the police, reparations (for slavery or colonisation), etc which don't get as much traction in Europe. On the other hand a lot of the traditional left-wing ideas like heavy state intervention, actual socialism, workers' rights are bigger in Europe and several countries have actual communist parties with parliamentary representation. But then again, most European countries are states for a specific ethnic group which would absolutely not fly in America, Canada, Australia etc. For instance, German right of return lets anyone of ethnic German descent from Eastern Europe claim German citizenship.
