The biggest mistake we humans make is bothering to get up in the morning. The world would be a much better place if we all died and there was no more humanity to pollute this planet. If we want to "save the planet" as everyone seems to be on about at the moment, the best way to do it is for us all to commit mass suicide. When I stop and look around me at the way people conduct their lives I despair. I also acknowledge that I am far from perfect myself. Take the floods the country is suffering from at the moment. We find people afraid to leave their flooded homes for fear of looters. We find people actually vandalizing water bowsers. These people should all be shot on sight. They are nothing but rodents, except for one thing - they give rodents a bad name.
If you go on holiday, you have to go through a load of extra security at the airport because of religion obsessed nutters who want to blow you into a thousand pieces. We have gangs of idiotic youths wearing hoods when it isn't even cold going around beating people up. We have a predominance of one particular group who think it good to carry guns and use them on each other. The list of evils is endless. If you have a happy contented life you are very lucky and probably oblivious to the crap that is going on around you.
If you look around the world and see the atrocities people inflict upon one another - all for, in their own minds, very good and laudable reasons. People are starving in Zimbabwe and North Korea while their leaders get fat. People are murdered because they change from one religion to another, while others are murdered in "honour killings" - almost always women.
Mankind is not made in the image of god because, clearly, there is no god. If he were, then god would be self evidently evil. Mankind is to this planet what a weeping sore is to a leper's back. So lets all do the best thing we can to save the planet from any more of this rubbish, and lets all just drop dead! I'll follow you......
