marriage or marriages

The reason I chose uncountable was that I wanted to emphasize the abstractness. Is my understanding incorrect? If so, please correct me. Thanks.

I believe in gay marriage

I believe in marriage

Both are correct when talking about marriage as an 'institution' 

Please go back to the earlier posts. I think Optilang and I have already provided the answer.

Thanks, Optilang, GG and Yoong Liat. I have no further question about the original question. I agree with GG's answer (arranged marriageS, gay marriage)

Yong Liat, this is a side question. I wonder why my question confused you and made you ask:

It is possible to use the uncountable in the first sentence?

What do you mean by 'uncountable'?

You suggested 'plural' or 'singular' instead of 'uncountable' in my question to make it clear, if I understand your reply correctly. The reason I chose uncountable is as follows:

As far as I know singular and plural are words associated with countable. For example

An apple (is singular)

Apples(is plural)

a gay marriage ( is singular)

gay marriages (is plural)

gay marrriage (is abstract/uncountable)

The reason I chose uncountable was that I wanted to emphasize the abstractness. Is my understanding incorrect? If so, please correct me. Thanks.

If I had used 'singular' or 'pural', it would have referred to one of the countable nouns, which was not what I wanted. Please let me know if my explanation is still unclear.

The system seems to have some problem. What I posted a short while ago, was not posted immediately after the last post by another member. Instead, it is above a  much earlier. post.

I think your computer is infected with a virus. :)

I see it here right before your most recent post.  In other words, it's on page 2.

I don't think my comqputer is infected with a virus. I've the latest anti-virus program installed on my computer.  Let's see on which page this post appears.

It appears on page 1 when it should appear on page 2 or 3.
