Can we just put this lie to rest. Economically maybe, socially very much not, for example abortion is much more restrictive in many parts of the EU than even Roe v Wade allowed. Or immigration, it is much harder to immigrate into Euorpe than it is to get into the US. There are dozens of other social issues Europe is far more conservative on than the US.
In terms of what the purpose and role of government is, Europe is far more classically liberal minded than the U.S.
EDIT: Now that Roe has been gutted by the very conservative Supreme Court your point about abortion is very much wrong. Outside of Poland and Malta, I think Europe has much more liberal views on abortion. Especially when you consider that healthcare is generally free at the point of service there.

The center of American politics have very much moved to the right the past 50 years. As such, a small rightward shift from the mean has the appearance of being moderate. What is considered radical left in the U.S. is left of center in European countries.
By quite a large margin more women lean leftward in the U.S. than rightward. Women are more discriminating when than men when looking for partners so it is expected to see the outcome in the link you posted. Tied to the paradox of tolerance, and the definite rightward shift of the center in American politics, we see that it is expected that left leaning people are less likely to associate with right leaning people than vice versa.
We had an insurrection 3 years ago that most people on the right fail to acknowledge as such. It doesn’t get much more radical than that. Far more people think Biden was illegitimately elected than that Trump was illegitimately elected. I could go on with more examples but I think it won’t be productive. Try reading about the historical political trends in the country dispassionately.
