The latest: Environmentalists blew up the BP oil rig in the Gulf of Mexico to make some point or other. It's brilliantly backward logic, of course, but it makes perfect sense to Limbaugh and his Dittoheads.
Here's the response of Media Matters, which keeps track of El Rushbo's own wackiness:
Today Limbaugh theorized that environmentalists may have been behind the explosion of an oil rig that is currently dumping thousands of gallons of oil into the Gulf of Mexico. Because the rig exploded one day before Earth Day…. And Earth Day was inspired by a river in Cleveland catching fire. And cap and trade was strongly criticized by "hardcore environmentalist whackos," and what better way to "head off more oil drilling" than by blowing up an oil rig? His logic is airtight. Somebody call Mensa.
