This is a good example of how 'patriarchy' has been misused to the point of meaninglessness. Putting frat boys and guys who won't let their daughters be educated together in the same box as if they have the same worldview is ridiculous.
This is like somebody saying the word 'precipitation' is meaningless because snow and rain are different
I dispute the analogy. There are sufficient differences in worldview between male dominated libertines and actual patriarchs to indicate they are different ideologies. Put another way, Barack Obama and Rosa Luxemberg might agree on two or three things and they are both opposed by the right, but calling them both socialists is just silly.
The social justice left has constructed a perfect bogeyman for themselves. They have defined "patriarchy" in such broad terms that they can identify almost any aspect of any culture as being resultant of the patriarchy, with little hope of escape from this evil god. The problem is that it is not a useful way of breaking down the world.
