In short, yes, gay marriage should be allowed. If marriage between a man and a woman is legal (as well as intermarriage) then why should it not be allowed between those of the same sex?

Those who argue that it shouldn't be allowed because marriage is of a particular religion that forbids anyone being gay then they should also agree that marriage should therefore have nothing to do with being a legal matter in which a couple gets benefits from getting married such as in the areas of medical, taxes, death, and more. If gay couples can't receive these rights, then no one else should. Everyone should therefore be reduced to what many gays have to due now and just have a ceremonoly marriage with no legal benefits.

Also those who are against it due to their religion need to realize that whether or not it is against their religion or not, that has nothing to do with it because ,last I checked, my country has the freedom of religion, meaning not everyone has to follow what one person believes. And in all honestly, a gay marriage will ,in the most, not affect the said person any more then it does now.

Another point people agrue is that gay marriage will lead to and allow what is not traditionally thought of as a family and to many, this is unacceptable. And to those people, I say that the traditional family of a mother and father has already become less popular then it was a even a few decades ago. In today's world, there are many forms of what is now considered a "family". There are those who are raised with only a single parent, those who are divorced, those who were born from a seregate and raised by a different couple, ect, are only a few examples. People need to realize that times change and that a major change is happening now whether they agree with it or not.

In the end, I believe gay marriage should be allowed with all the legal rights and benefits that a marriage between a man and a woman have and those who think otherwise are basicly just discriminating against what is different from themselves. Eventually gay marriage will be legallize just as intermarriage has been and future generations will look down upon those who are against gay marriage now as we look down upon those who disagreed with intermarriage. Simple as that.

To be trully considered and answered, this question needs more information. For example, what one religion would everyone believe in? If it is a religion that contains racism and/or allows murder or death , then no, the world would not be in a "better place", but if it is one in which there is actually peace, love, and everyone cared for one another and so on, then yes the world would be better off.

But again this is based off of what one person or majority group would consider better for the world and in the end is subjected to perception, therefore becoming impossible to actually answer because what one person would believe to be a "better world" would be the complete opposite of someone else. In the end, due to human nature to create new ideas and disagree, we would end up where we are now with religion-everyone having their own belief that they are right and others are wrong, thus leading to war, and many other things. In a sense, history would repeat itself with all that is good and all that is bad.

Also, even if everyone believed in one religion it wouldn't neccessarliy fixed all of the other major problems we face in the world today such as famine, illness, death, ect. So the degree in which the world became a "better place" can't be measured and may in fact be only a very small improvment of what we have now if at all. This is why the world would most likely not be a better place if all believed in the same religion.
