The only sadness I have in life is the fact that I am not famous enough to really irritate activists.
One need not be famous to do so, just depends on the scale upon which one wants to irritate. Take a look at my profile for one example of irritating these fools on a local level.
Or, try this: Take your Weber, load it in your truck and grill hamburgers in front of a vegetarian restaurant. That really ticks them off. (check local permits though).
You just have to do it on an individual basis.
For example: one fine winter day, I boarded the commuter train from Chicago, wearing my new leather jacket. The train was almost full. Almost all the seats on the train car were filled. There were only 3 seats that had an open spot I could sit down in. My decision on which one to sit in was made when I noticed that one open seat was next to a young woman wearing a PETA button.
