Why is it that adults preach about democracy and how great it is when really if you're under 18 your parents are like dictators?

Situation: married man and unmarried woman on the verge of involvement. Does the woman have a responsibility to protect his marriage vows, or is the responsibility solely his? In the absence of any specific religious doctrine, how would you frame a principle to facilitate discrimination about where responsibility begins and ends?

Why do the laws of morality and the laws of nature seem to be completely opposite one another? For example, most moral codes encourage monogamy while the theory of evolution states the strongest seed should be spread around.

What is the difference between ethics and morality?

If science (i.e. evolutionary psychology) can explain why I have the morality I do, does that mean morality is subjective? If what I believe about morality is just a product of my evolution and my upbringing, can I still expect other people to live up to my principles even though they may have had a different upbringing? What about myself? Can I still hold myself to my own standards or am I being deceived by my evolution into thinking it would be wrong to do so?

For what reason should beliefs of others be honored or respected? That is to say, if something I say makes another uncomfortable because of their belief, what reason do I have to not say it? I have heard many times people say, "Don't say that, it will insult people because of their beliefs." Given this reason, if there were a person who was deeply insulted by the word "is" in any conjugation I would have to really tip toe around any speech! I suppose I am talking mostly about religious/superstitious belief. There doesn't seem to be any reason to respect beliefs in this regard when the belief may or may not be true. My second question: Did I just answer my own question?

I am married to a man who earns a considerable amount of money doing a job he enjoys. It is possible for me to earn a similar amount of money, but I now feel considerable discomfort in the profession that over the years has allowed me to do so. My preferred work (writing fiction) will bring in no money in the short term and has little chance of a lot of money in the end. Is it ethical to choose to earn less, and yet to share the rewards of my husband's salary - the big house, nice car, holidays and so on?

Is it philosophically defensible, or morally right, to inculcate your child to an organized religion when you yourself do not firmly believe in it? Along the same line, is there anything wrong about avoiding religious topics with your child with the intent that the child will choose her own set of beliefs when she becomes more mature?

What if two politicians are running for office and neither is qualified? Is there an ethical duty to vote for the lesser of two evils, even if doing so results in putting a stamp of approval on an unqualified candidate? Or is there an ethical duty not to vote for either of them, since doing so would give them legitimacy?

In googling around for an old boyfriend, I found only these details about him: 1) that he and his wife live on the opposite coast and have an unlisted phone number; and 2) that he, his brother, and sister all have unclaimed funds in a bank in the city where they were born and lived until they were teenagers, when their mother moved them to another state. I also discovered his brother's address and phone number. Would it be personally intrusive (thereby ethically questionable) to send a letter to the brother, letting him know about the unclaimed funds?
