> * You think to be friends you need people with the same hobbies and interests.
At least in that point there is some truth to it. What activities will you engage in with people, if you do not share hobbies or interests? Activities will be quite limited, unless you discover some shared interest or hobby. Maybe your shared interest will be once a week sitting in a café and talking about your job. As long as it is a shared interest, you got at least something to do with the other person.
Socialization in many countries around the world is still very much having strong bias for men and women roles and interests. Without high awareness of this, it is also very difficult for parents to do anything about this. Children are usually not 24/7 with their parents either. They spend a lot of time in other institutions like kindergarden and school, where they usually face a mainstream bias.
This means, that quite often there is a trend for men and women to also have different hobbies and interests. There is of course overlap in many areas, but not everywhere. It is slowly changing, but it will still take a long time. Just to give examples:
When I studied CS, only 10% were women. Looking at biology and psychology for example, we have almost the opposite situation.
