First you need to know how to spell it…then you need to be able to say it without stumbling. Once you have mastered those two, you will probably take longer to nail down any sort of understanding of what it is and how it works. Ben Shapiro does a fine job so he must have been at it for a while.
In a nutshell, intersectionality is all about the hierarchy of victimhood and where you find yourself in that structure. Once you have done the math and come up with just how many “intersecting” victim groups you identify with, then you can determine how important your thoughts are to the world at large.
In the leftist world, this hierarchy begins with the straight white mail on the bottom and piles the many victim groups on top of him. That way, his voice is usually insignificant or not heard at all. Only by suppressing someone else, the leftist believe, can your voice be heard. If you are a straight white male, get over it and accept that your thoughts mean nothing to the left. Sorry. You lose.
