(CNN)  -- Not content to sit quietly at home eating their tofu cutlets, more and more vegetarians, it seems, are taking action, trying to get the carnivorous masses to change their ways.





Of course, the meat-free have been trying to win people over to their cause since the time of Pythagoras. But lately, activists are trying more in-your-face tactics.





For Lierre Keith, author of "The Vegetarian Myth," the "in-your-face" part is quite literal. A former vegetarian who has publicly recanted, she was lecturing in San Francisco, California, last week, when three masked assailants shouted "Go vegan!" and lobbed chili pepper-laced pies at her.





Even in hard-core vegan circles -- which exclude using animal-based products for food, clothing, medicine or any other purpose -- such borderline-violent exploits are controversial.





More common is the approach of folks like newly converted talk show host Ellen Degeneres, who has been sharing recipes for vegan nachos along with her philosophy.





Still, recipes only go so far. And, more to the point, they don't get as much media attention. For many vegan and vegetarian activists, getting coverage is an art.





PETA





If you've ever read about a particularly outrageous pro-vegetarian campaign, there's a good chance that People for the Ethical Treatment of Animals was behind it. The folks at PETA seem to be firm believers in the idea that "all media attention is good media attention," and the more shocking or ridiculous the stunt, the more media outlets will pick up the story.





PETA was laughed at when it tried to rebrand fish as "sea kittens," in hopes that the more cuddly name would make seafood a less appealing mealtime choice. It was criticized for the suggestion that recently deceased Oscar G. Mayer should be buried with his company's hot dog-shaped Wienermobile.





After British celebrity chef Gordon Ramsay cooked up horse meat on his show, PETA UK dumped a ton of manure outside his London restaurant.





Plenty of ecological activists cringe at these kinds of prankish maneuvers, but they do get noticed. And that, apparently, is the point.





Why else would PETA organize an army of zombies to protest outside of KFC restaurants?





Not content to oppose meat-eating in the real world, PETA also took a swipe at virtual carnivorousness: In response to the Nintendo DS game "Cooking Mama," the group released its own bloody version.





And, as anyone who's seen its anti-fur posters knows, PETA is well aware that sex sells. The group got the granddaughter of Argentinean revolutionary Che Guevara to pose wearing nothing but a bandolier filled with carrots.





Last, year PETA proposed a too-racy-for-TV "vegetarians have better sex" Super Bowl commercial, guaranteeing plenty of coverage when -- surprise! -- NBC rejected the ad.





PETA also brings its soft-core approach to the streets with its "Lettuce Ladies" campaign: young models, clad in a few strategically placed leaves, handing out veggie hot dogs.





The group has enlisted Pamela Anderson and Elizabeth Berkley to pose for the Lettuce Ladies Web site (find it yourself) -- probably the best thing that's happened to their careers in years. Is there tofu wresting? Yes, there is tofu wrestling.





Casa Diablo





PETA is not alone in combining feminine pulchritude and an anti-meat agenda. A couple of years back, Portland, Oregon, resident Johnny Diablo got a bunch of media attention when he opened Casa Diablo, the world's first vegan strip club.





Serving veggie burgers with a side of nudity (or maybe the other way around) might seem to be just a publicity stunt. (The fact that Diablo tried to put the club up for sale shortly after opening would seem to suggest that.)





But Mr. Diablo is an earnest vegan himself, and he's apparently retained ownership of Casa Diablo, though reviews -- of both the cuisine and the more fleshy attractions -- are decidedly mixed
