Should homosexuality be considered a criminal offense/act? Also, what's your view on Morality?

Ok Escapist community, this is a two part question, the first on justification for cultural imperialism and the second on the different views of morality.

First issue:
Now I just finished reading an article on Malawi law that bands homosexuals and one particular section of the article made me feel uneasy. It stated that,

"On Tuesday, US Secretary of State Hillary Clinton said the US would use foreign aid to encourage countries to decriminalise homosexuality. UK Prime Minister David Cameron expressed a similar view in October, saying that gay rights were a human right."

The article later went on to state that "Homosexual acts are illegal in most African countries, where they are often viewed as un-Christian and un-Islamic" and the President of Malawi, Bingu wa Mutharika, called homosexuality "evil and very bad before the eyes of God".

I don't know how to feel about the whole situation, because while I don't think it should considered a criminal act, I am also uncomfortable with the reactions I see from the Western political leaders, the reason being is that their attempts to manipulate the laws in Malawai on homosexuality come off as a subtle form of cultural imperialism. What I mean is do Western Nations have the right to manipulate the laws of other countries if they go against the social norms of Western culture? Is it wrong for western nations to try to manipulate others so that they agree with the social norms of western culture?

Here a few other articles about other African countries against homosexuality and how the West is responding:

Second Issue:
When I read the article on Malawai, it made me think of another question on morality, does Moral Universalism exist, or does Moral Relativism exist? I bring this up because, I don't think homosexuality should be outlawed and that it is wrong to do otherwise, and I think that if I was to believe in Moral Universalism, then I would also feel that it is wrong for those African countries to have such a law. However, if I subscribe to the idea that Moral Relativism exist, then while I might not agree with such laws, I guess I would feel that those laws were just a reflection of the morals of the various African cultures and not automatically "wrong". Tbh, I'm not sure how I would feel about the African laws if I followed the idea of Moral Nihilism.Articles such as these give me the impression that Western leaders believe in the idea of Moral Universalism, but what about you? People of Escapist, do you believe in Moral Universalism, Moral Relativism, or Moral Nihilism?

NOTE: For the poll answers, CI stands for Cultural Imperialism, MU stands for Moral Universalism, MR stands for Moral Relativism, an MN stands for Moral Nihilism.

People in at least one african nation are in danger of being fucking executed for being gay.

I have very little problem with the idea of cultural imperialism for the purposes of preventing the institutionalized murder of thousands.

and /thread at the first post. It probably is morally questionable to deny these countries aid based on their stance on Gay rights. However, on the other hand it is very definitely morally wrong to persecute (or worse) an entire sub-culture of your own society just for being different to you; and when we fund governments, by extension we are funding their beliefs and their actions. So if we are committed to Gay rights we can't associate ourselves with people who actively oppress Homosexuals.

would you feel the same way if the African countries were banning bestiality or pedophilia and the West was denying them aid because of the creation of such laws? Wouldn't people who are attracted to children or animals also be an "entire sub-culture of your own society"? Wouldn't those laws be a form of persecution?
