It's a bit weird to see the Western world or at least some organizations in it treat adult Ugandan legislators like they're children who can't be held responsible for their own laws, especially when the law is really not very different than what's on the books in other African nations (e.g., Sudan, Mauritania, Gambia, etc.) that don't get such bad publicity for them, and when there are other laws on the books in other nations that similarly make living according to something that offends the majority a capital offense (e.g., laws criminalizing conversion to Christianity from Islam in Egypt), the same people calling Uganda a hateful trash country often say "it's their law! It's their society! It's their country!" Coptic and other Egyptian human rights organizations in the diaspora have for years been trying to get the US aid given to Egypt tied to an improvement in human rights and a change in the laws negatively affecting religious minorities like the Copts, Baha'is and others (e.g., the 1981 amendment to the constitution placing Islamic Sharia as the supreme and inviolable source of law in the country), but that's a political hot potato that nobody in the West will touch. What a bunch of damn hypocrites we are.
That said, I really don't think that living in a way that offends the majority ought to be illegal in the first place, obviously. Did gays cause genocide? No. Do gays cause earthquakes? No. Do gays cause other people to become gay? No. Yet these are all things believed by people of various religious faiths (not just Christianity), and even no religious faith (socialist Albania, famous as
the world's first "officially atheist" country, mandated up to 10 years in prison for the crime of being homosexual, according to article 137 of the Crimes against Societal Morals section of the Penal Code, which was not done away with officially until 1995, long after the country had stopped being socialist). What is a law going to do to change these people's minds about this stuff? Not much, whether it is positive or negative towards the people they already believe these myths about. Those who think that gays are the downfall of all society will continue to think so, same as they do in the West -- and those who think that homosexuality is to be promoted as societal good in the name of equality and love and such will continue to think so, too. We are really not that different than Uganda, even though our laws are trending in the opposite direction over the past 15 years or so (speaking from an American perspective; I know Europe has been much more open to this stuff for years).
