Gender roles in society

So I’m all for equal pay and equal rights, but the discussion in class the other day about gender roles really made me question is there anything really wrong with the way we divide the work load between genders? To me it makes a lot more sense to have men specialized towards tasks which they are more likely to succeed at and the same for women. Unlike race there are vast differences in the biology of men and women, from hormone levels which regulate temperament and emotions to physical stature and build. Men being physically bigger means they are more apt to succeed at hard labor jobs than women, on the other hand women tend to have more patience and concern for others which makes them more suitable for other careers in which they likely outperform men. Neither side is in any way superior to the other but to deny that each gender possess a different skill set is kind of non-sense. There will of course always be exceptions, but for the majority of society the way we have divided the task seems to work just fine. Yes women in the past have been expected to cook and clean for the family, but no one seems to mention that in most household tasks such as yard work, car repairs, fixing things and anything remotely dangerous is expected to be done by the man of the house. We can either all do a bit of everything to a mediocre level, or we can divide tasks based on the actual skills of each sex.
