Now that Anonymous released their personal contact info, we can protest every time one of them gets knocked up, married, or choses life. We can round up some people from an abortion clinic, and have them hold up signs by the gynecologist's office.
Here's shooting some ideas around, feel free to work with it:
1. "you should have swallowed"
2. "coat hangers are your friends"
3. "moar butt secks, less mutant children"
4. not really a slogan, but handing out free tickets to the most hazardous and bumpy roller coaster rides 6-Flags ever made
