I was thrown into a brief quandary when I thought that the "hacker" group Anonymous was trying to get us to boycott Vanity Fair because of the Koch Brothers. What has Graydon gotten up to! I thought. But no, they mean the paper plates and napkins. Oh.
If you can manage to not purchase those or their similar products (Brawny!), you can also probably forego all the Koch Brothers' Invista products, including Stainmaster carpeting (ew) and Lycra. You can avoid Lycra, right? Also maybe look out for like, oil and natural gas. Good luck with that!
