You're a murderer if you use petroluem...

I've said it before, I say it again...by using petroluem, you're a murderer at least three times:

2 - killing the Arabs in oil producing dictatorships where everyone is poor
3 - killing the desperate people that poor arab terrorists kill

there's more but I can't think right now... you can think about this picture and whether or not you should be riding a bike:
