Its reasonable to all ppl who think.
If everyone were to steal, nothing would be produced. Of course, this would never happen because people would start producing for themselves at least because they need produce. Those that steal are supported by those that produce more than they need, but it could never happen that everyone steals.
So there will always be an equilibrium between these extremes. I think the same is true of homosexuality. I think probably the main reason that people choose to live as homosexuals to the degree that they do (I'm not saying that all homosexuals choose it) is because having children doesn't seem to mean much. The Earth has 6 billion people, what's one or two more worth? Also there's education to pay for and scarcity of jobs and, and, and...
Let's face it, children aren't what they used to be. Many people still choose it and they always will, but less choose it than would otherwise. And if you decide not to have children and you feel you have homosexual tendencies or would fit better within society as a homosexual, who is to say you shouldn't do so?
I think (and perhaps I'm wrong) that marriages don't work because families don't work. Modern people don't care that much for family life, it's that simple. In the past the family was important because families tended farmland or whatever, but families don't need to stick together anymore. This is the information age, the atomic family is out of date, obsolete.
Although it must be said that having children still seems to be seen as something good in at least one sense, but this sense is perverse because a family is seen as a sign of status. You "have" children but strangers take care of them and educate them, you give them money to make them happy because you don't want to get too emotionally involved. You "have" children in name only because that's all that counts.
And then do you wonder why marriages fail? Marriage is a lie. Most who stand in church (or wherever) and say "for better or worse" are lying through their teeth. Think about it. It's a meaningless ritual, just something one does.
So what is the problem? I think the problem is the unwillingness of people to accept change. Traditions are for old people who have lost the passion for life. The old conception of a family doesn't fit in our society. The old conceptions of love and of relationships don't fit in our society. I don't see it as sensible to speak of what is 'preferable' when what you consider to be preferable doesn't fit.
I see our growing independence as good. Liberating change is good, why resist it? Sexual liberation is simply the liberation of people's action from old dogmas, and I think that is a very good thing. In the same way, I see independence of women in society as an extremely good thing. Would you want to put women back in their traditional role? I think that would be heinously selfish.
I think independence and liberation are preferable.
