Because they're mostly halfwits who realise that they are just warmongering rednecks??? I don't know.
Don't really want to encourage you here, but suicide is a state of mind induced by the feeling that you are worthless or life is not worth living. Thoughts such as these can be the result of a chemical imbalance in the brain. Factoid 1. There are drugs on the market that can alleviate these thoughts. Factoid 2. And no that doesn't mean I agree with every parent putting their kids on drugs if some nancy doctor says they have ADD. I believe a lot of that is caused by diet and modern society anyway.
