I say give these animal "rights" activists a taste of their own medicine. But keep it legal. Eventually they will provide us with legal clearance to mow them down (which is what they all deserve for terrorism).
While I'm not exactly proud of it now, we had a very staunch PETA woman living a few doors down from us where I grew up. She'd lecture us on this or that if she got the chance and made a habit of yelling at local farmers.
So, of course, being teenagers, we snuck out at night and would hang pieces of meat from her clothesline. (I can't believe I'm writing this...) At the time, it was hilarious.
