a simple question that few actually seem to ask themselves while they are busy shoving shit down their throat.
of course, the first reason is simple SURVIVAL,
but seeing as how that is not so much an issue for the great majority of the United States, it is the second which we are most concerned about - PLEASURE
Now, if you are eating meat for a reason other than instinctual survival, it is pretty much a guarantee that you are consuming meat out of sheer pleasure. Of course, no matter what the method of slaughter, the only way meat can reach your plate is for an animal to suffer and die. if you are engaging in an act of pleasure that can only result from the pain of another creature, that is perverse and sadistic.
to that end, anyone who claims to be a peaceful person but continues to eat meat is ignorant at best, and a sick sadistic hypocrite at worst.
If you cannot watch your food during all stages of its production, you have a problem and need to ask yourself why you can eat the finished product, so long as you do not see what it took for it to get to your plate. simply, that is wrong.
I have no qualms about personally taking part in each and every step of production for every single piece of food i consume - if you cannot say the same, please examine what you are using for survival, and what you are using for pleasure.
