Mammalian psychology and migrant antipathy

I look into the level of human psychology that is communal; the mammalian part of our identity.   Women are supposed to be more at home here than men, at least so says folk wisdom.  This is the relational part of our beings -- how we experience ourselves in terms of our families, our sense of peer group pressure and relative economic success.  Frankly, I'm not drawn by these at all, but one is not free to decide not to be.
