This is an interesting question to answer. There are many differences between the genders, and many are seen in America. However, the reasons these differences exist have split people pretty evenly on every issue. The PEW Research Center did a study in 2017 to see whether people thought certain aspects of biology or social expectations contributed to how people perceived gender differences.
They found an almost fifty fifty split on every issue when gender of the responder was ignored. When specifically asking men and women, there was a bigger difference between the answers, and some were complete opposites. For example, more women believe that how people express their feelings are influenced by societal aspects while more men believe that this same thing is more influenced by biology.
