It has come to my attention that gender roles, or seperating genders into groups may in part be the result of aristocratic thinking. This can be seen in phrases like "Man's Common Sense Vs Women's Intuition" Which gives men as a group Sensing qualities and gives women as a group Intuitive qualities. It can also be seen in the fact that although the seperation of types should be 50/50 for each dichotomy, for logic/ethics the reported average is more like 60% men/40% women for logic and the reverse for ethics.
When you think of someone who is exceptionally manly, you think of a healthy male ST, who is strong and sharp, but not always good with emotions or spiritual awareness. When you think of someone who is exceptionally womanly, you think of a healthy female NF, who although frail and sensitive can be a great spiritual and emotional upbringer for her children. Some Male ST's and Female NF's can be seen encouraging their sex to act more like them, if only subtly. Democratic types (NTs and SFs) of either sex are not likely to feel much affected by these roles, because they qualify enough (halfway) in their role to be comfortable, but not enough to be proud or think anything more of their role. But when it comes to Male NF's and Female ST's, you see a lot more cases of gender confusion, because they do feel connected with these roles, but often it's the opposite role. I also notice there is a small increase in the proportion of gay/bi NF's and lesbian/bi ST's.
This is all just speculation and I'm not saying saying all gays are either humanitarians or pragmatists, but these have just been some of my observations while studying clubs.
