Marcellus, coal, etc. vs. oil

I have a question. Why is it that we can drill for natural gas, dig for coal, etc, but yet not drill for oil without people getting their fucking panties in a bunch? What the hell is the difference? Drill for oil, for God's sake. What can it hurt? All it can do is help us with our energy costs. Oh, I know some of you will say "well, that's just a drop in the bucket." My retort is, at what point do you finally fucking say "enough is enough" and we start doing our own thing as a country??? Think about that, please, and get back to me when you have an intelligent response that makes sense to the contrary of this blog post. Thank you.
