He's a poet, and it sounds like he has already explained this as a description of the irrational shit going on his head. Shit he knows is irrational. So he's talking about it, getting it out. How is that not 'dealing with it?'

Very fair point. Though a slam poem about fighting the many injustices of the patriarchy in general may not have the same punch to it. Hmm

I get that, and I imagine the whole 'delicate flower' trope is pretty damn tiresome. But from a purely pragmatic POV...if he was talking about his son and cartoonishly threatening violence against future girlfriends...Well, that doesn't really seem to work for a whole bunch of reasons, does it?

And as the crowd laughs and applauds him for being threatening (he's got a toy cap gun prop), it's hard not to feel like there's a bit of agency robbed of the daughter, and an old, very familiar narrative playing out: The patriarch shielding the woman from the world.
