One of FFTF's co-founders once told CNN that "there's this academic theory ... if you ban the ability of people to share cat photos, they'll start protesting en masse." We proved it during #SOPA. Now we've got the Internet Defense League, a network of superhero websites that keep the kittens of the net safe at night. Get your IDL Cat Signal t-shirt to show all your friends that you're on team internet. All of our shirts are printed on American Apparel unisex 50/50 cotton blend tees.
