I like this artwork a lot.
The context is that, in 1979, Jenny Holzer wrote 30 or so essays, each consisting of exactly 100 words over 20 lines. She pasted copies all around New York, so members of the public would just stumble upon one of them while going about their business. But nowadays the essays are more likely to be seen in an art gallery, positioned in a big, repeating grid for easy consumption.
The contents of the essays vary. Some are undeniably fascist, some are feminist-punk , some are religious, but all of them are written with anger and passion. If you read through all the essays, there's a good chance that some of the messages will revolt you and some might even resonate with you.
Going from extreme to extreme, you get a whiplash. You start to wonder what kind of person would write such material (or at least, who Holzer was drawing inspiration from). It's a lot of voices, a lot of rage (much of it misplaced), delivered as a big information slurry.
It's a neat encapsulation of the worst parts of social media, written before the Internet was even a thing.
