That "joke" contains highly offensive subtext. What it really translates to in rapespeak is this.
A rapist, presumably just after raping someone, sees another rapist walking down the street with a suitcase full of rape tools.
"Who are you going to rape with those?"
"Oh, lots of people. But first I have to go to court to get my rape case thrown out. Because of my white male privilege, I will get away with it. Then, after that, it's rape rape rape rape rape."
"Isn't white privilege great?"
So then the rapist comes back later, with a ladder.
"So, what are you doing with that?"
"Well, I'm going to climb up a wall and jump in a window and rape someone, obviously!"
All very easy to see to one versed in the coded language of male rapists.
