We told you last week about a disturbing pattern of animals turning up dead after pious animal “rights” activists intervene in the natural order of things. We didn’t even mention the more than 14,400 dogs and cats that have perished at the hands of People for the Ethical Treatment of Animals (PETA), whose employees should know better. And now this: Last night Boston-area firefighters battled a massive blaze at a pet shop in the suburb of Cambridge. On the exterior brick wall of the burning building, they found this unmistakable animal-rights graffiti: “No more exploitation of animals.”

By all means, let’s save them from exploitation. By burning them alive. Boston’s TV-4 reports that “snakes, turtles, lizards, and fish were all killed in the fire.” And firefighters had to cope with live snakes — some potentially poisonous — while putting the fire out.

The animal rights movement appears to be adopting that Vietnam-era canard: “We had to destroy the village to save it.” And fire officials in Cambridge are calling this what it is: an act of “terrorism.” Click here and here to watch local news stories about this disturbing crime.
