There are many reasons I don't subscribe to the animal rights concept. One is that the animals we award rights to is completely arbitrary. I've had a mouse infestation lately and I've decapitated close to a dozen mice with wire traps. Living, breathing, intelligent mammals who meant me no harm or malice. Do I deserve to die in a car crash? If not, how many dead mice equal one dead dog? Would the situation be different if I killed the mice with a tiny little chainsaw?

"If you own a computer, odds are you have seen Loose Change, a slickly-produced viral internet video making the case that the U.S. government planned and executed the 9/11 attacks. No, I don't know why it's called "Loose Change."

If you haven't seen it yet, you will soon. The Loose Changers will make sure of it. They sell this thing like they're getting a commission. In a single day I had four different people on four different forums try to get me to watch it.

2. The hijacked planes didn't bring down the World Trade Center, the buildings were wired with explosives ahead of time;

3. Flight 93 didn't crash in Pennsylvania and in fact landed safely elsewhere. The passengers were in on the conspiracy.

They've sold more than 100,000 copies of this thing on DVD. It's been downloaded millions of times.

But is it bullshit?

There are basically two views on the subject, and I intend to provide both equally. You can make up your own mind. One side says...
