Yeah, yeah. Art is "subjective" and it's all in the eye of the beholder. I know the drill.
But when that "art" is a none too subtle threat to stalk and have sex with the daughter of the person on the receiving end of the "art", it starts to sound a little like a ransom note.
I strongly suspect that if some guy sent you some "art" threatening to stalk and (forgive me) screw your daughter, you wouldn't care a whit about his politics, and you wouldn't care a whit how artistically he delivered the threat.
I read it. I have two teenage daughters. I saw this poem as a satirical (rather off colored, but satirical nonetheless) poem aimed at revealing something about someone’s character (the fact that they are a hypocritical “compassionate” liberal “tolerant” of so many views) that they didn’t want to see and it shocked them.
Had I received this, I probably would have questioned him, but I wouldn't have kicked him out of my class without giving him a chance to explain. Then again, I'm not a "tolerant" liberal either. ;o)
Would I have written this? No. I don't put overt sexual commentaries (fact, fiction or fantasized) into my writing. Have I written something scathing and biting aimed at a liberal professor? Absolutely! (and I still got an A on it...but, my professor was more able to appreciate art as a form of expression)
