Most people out there would misunderstand the word patriarchy. They take it to mean: fatherly-rule or “through rule of the son from the father”.
In-fact more than 200 years ago they constructed a new word matriarchy to counter this “sexism”. This new word meant passing of rights through mother’s side.
While societies have been greatly sexist and favoring unfavorable and prejudiced practices for quite long patriarchy actually meant “family rule” and not “male member rule”.
This confusion arise because of misunderstanding of 2 close and interconnected

Everyone was thinking in terms of physics (i.e. force). Einstein knew one part of that is maths, pure maths. Force is physics because of mass. But acceleration is geometry, its the shape of your trajectory and its maths.
Imagine a pipe which is horizontally fitted across a wall. Now water jet is flowing through it, inside of it. Now that wall is on a rotating base. You rotated the wall downwards. The pipe is inclined downward, water streams across downward.
Now imagine you have a torch light fixed to one end cap. You get a horizontal output of light. Now the wall is rotated downward, obviously the light will also stream across downwards.
The mass of the water or light did not matter. Because they are guided by the pipe and wall.
The same thing happens in the universe. The space is what carries mass, and it carries all physical phenomena including light. When that space itself is inclined (warped, rotated or receded or whatever) light would follow a curved trajectory just like any object of mass would. Space is what holds them, matter and light. Space curves under gravity.
