If what makes something immoral is any act that harms someone, would deliberately harming oneself count as an immoral act? And if some other person who is harmed agreed to be harmed, would that be immoral?

What constitutes a duty? I read somewhere that the elderly who are very ill have a “duty to die” in order to relieve taxpayers of taxes to pay for the elderly’s healthcare. Is this assessment fair? Do the elderly have a duty to kill themselves if they are already being a burden to others and society in general?

Does insult in whatever context count as a moral wrong?

One important trait of moral principles is that they should be impartial. They should not favor one person over the other simply because they are two different individuals. But in my country, we have laws giving special considerations to senior citizens and persons with disabilities and pregnant women. These groups of people are given special lanes at fastfood restaurants, cinemas and bank lanes. I sometimes feel unjustly treated when I spent an hour waiting in line while a senior citizen come in, make his transactions and leave the place in just a minute. I am fully aware that the reason they are treated in such a special way is because of their special conditions but it seems that the treatment is still unfair. After all, whatever they may suffer for waiting long in line are possibilities that I myself can experience. My questions then are: Are these special treatments unjust for the majority of us who are not in the same conditions? Do these violate the condition that moral principles should by nature...

Is it a valid argument that it is okay for someone to be homosexual because they were "born that way?" This argument seems to lack merit to me, and I believe the reasoning should be that there is nothing morally wrong with it aside from having certain religious conflicts. Pedophiles could be born the way they are, but nobody condones their actions, because there is something arguably wrong with what they want to do. I just seek another point of view on these issues, and possibly a few examples of things that may in fact be morally justified simply because one was born a certain way.

Is it consistent to be a libertarian while opposing suicide on moral grounds?

If technology advances to the point of recreating the world almost perfectly in a virtual reality (i.e. The Matrix), would it be morally acceptable to "move" into that world indefinitely? Let us assume there is a moral disparity between someone with/without family, friends, attachments moving into this virtual reality. Let us also assume there is no cost to sustain anyone's well-being in this distant future, either in this virtual world or the real world, such as rent or food. Perhaps in this virtual world there are new fun things to do, like flying freely, that in the real world one could not do. There is seemingly no catch to this, but is there a moral obligation to remain in the "real world" and do "real things?"

To a philosopher, there likely comes a time when the error in another's crazy ideas -say, at a party or dinner- can be so apparent as to invite some criticism. What's a good moral position on whether to correct someone's logic when it's uninvited and suspectedly unwelcome? Idea eg. UFOs, 'crystals', ESP, conspiracies, etc.

Is terrorism ever justified?

Moral disagreements seem to suggest that there may be an objective moral truth out there but it seems next to impossible to discern about it. Is there a way out of intractably difficult moral disagreements so that both opposing sides will be able to discern the truth of the matter being discussed, or the situation is just hopeless?
