Your criteria for weakness is based upon your own self-righteousness, I can smoke casually, chain smoke, or not at all . Support a real critera, you know how many people that are far more brilliant and revolutionary have hade substance problems? Do you judge based on any impulse one cannot control? I can smoke casually, dont buy them, but I believe in the right to ones own body. You break up everything into black and white truisms and someone that is in the middle has nowhere but your sides to exist within. This is not a good model for actually having a conversation, it is a lack of interpersonal intelligence...no offense. Believe, I am stupid if you must but most of America is overweight that will kill you too. You make a flawed argument here, I am here to converse
