Okay, so there's been some confusion as to what exactly my concept of morality would be. I had initially accused a few people of being dishonest in misrepresenting me on this, but I have to concede that maybe just didn't understand it. So I apologize for being hasty in that accusation. Allow me to lay it out; I will then be happy to take questions:
In my view, morality as objectively defined according to whether or not it brings about happiness or causes suffering. That action is moral which increases happiness; that action is immoral which causes suffering. This is an objective definition.
Of course, there will be some subjectivity in how happiness and suffering are determined. In some situations, they will directly conflict with each other. For example, if I shoot a home invader who was going to rape my wife, I have prevented her suffering but caused suffering to the the home invader. In these situations, a moral dilemma results.
In some cases, happiness or suffering will conflict with other ideals. For example, if I am a shiftless bum who refuses to get a job, I suffer from lack of money to buy food or pay rent. So others might volunteer to give me money to ease that suffering. However, compelling someone to give me money conflicts with other ideals, such as our right as individuals to do as we please with our money (that is, the ideal of private property), or the idea that individuals should take responsibility for themselves and get a job (that is, the ideal of personal responsibility). These situations also result in a moral dilemma.
When a person faces a moral dilemma, it is up to that person to resolve it on their own. There are no hard-and-fast rules to dictate what should be done in each situation. The individual must decide on his or her own and must be prepared to face the consequences of whatever they decided. For example, if a home invader were going to rape my wife, I'd shoot him without hesitation; I would rather face the legal consequences of doing so than face the consequences of what happens to my wife if I don't.
There are also situations in which society as a whole faces moral dilemmas. When this happens, people work together as a society to provide rules for how to resolve them. For example, the shiftless bum could apply for welfare, and society's rules would determine if he or she meets the criteria to get it.
In some cases, our personal senses of morality conflict with society's rules. For example, I believe that people should be allowed to smoke pot for fun if they want to. However, as a society, we have decided that this is against the rules (in all but two states). I have two options: follow the rules in the name of deferring to society, or break the rules in accordance with my own sense of morality. In either case, I am responsible for the consequences, and whichever I decide, I am also within my rights to work with others in society to get those rules changed.
So the bottom line is that I believe morality to be objectively defined but subjectively applied. I would never claim that my personal sense of right and wrong should be imposed on everyone, and I apologize if I ever implied as much. Ultimately, the need to live together in society forces people to work together to set rules for what is right and wrong, and these rules necessarily change over time with the desires and needs of the society. Such is the beauty of living in a society with a representative government; individuals get to participate in shaping the morality of the society as a whole.
I hope that makes more sense than how I've explained it up to this point. I'd like to thank everyone who has challenged me on various points of this, as it forces me to make sure that my ideas are well-examined and clearly-expressed.
I welcome your feedback.
