For most Irish people, the most striking thing about their new prime minister, Leo Varadkar, is that he is very young. (At 38, he is the country's youngest leader ever.) It's mainly the foreign press that goes on about the fact that he is a) half-Indian, and b) gay.
Mr Varadkar himself, the son of a doctor from India and a nurse from Ireland who met while working in a hospital in southern England, is definitely not keen on being seen as a symbol of changing public attitudes: "I'm not a half-Indian politician, or a doctor politician or a gay politician, for that matter. It's just part of who I am. It doesn't define me."
No, it doesn't, but it's still worth considering what it tells us not just about Ireland, but about the West as a whole, and even about the world.
Gwynne Dyer is an independent journalist whose articles are published in 45 countries.
Homosexuality was legalised in England in 1967, and it was decriminalised in Canada the following year. It only became legal in Ireland a quarter-century later, in 1993. But two years ago same-sex marriage was made legal in Ireland by a referendum in which 62% of the voters said yes.
Well, we already knew that Ireland had changed. It has lots of immigrants now -- one in every eight people is foreign-born -- and the political power of the Catholic Church has collapsed. So it's no longer a surprise that an Indo-Irish gay man can become prime minister. But what about Serbia?
Two-thirds of Serbians think that homosexuality is an illness, and almost four-fifths believe that gay people should stay in the closet. But Ana Brnabic is an out and proud lesbian, and she has just been appointed prime minister of Serbia. She is also of Croatian descent. How has this happened?
Ms Brnabic was appointed by Aleksandar Vucic, who was prime minister himself until he ascended to the presidency in last month's election.
The prime minister is constitutionally the most powerful person in the government, but Ms Brnabic is a technocrat, not really a politician. It is widely expected that she will concentrate on making the trains run on time, so to speak, and leave the sensitive political decisions to Mr Vucic.
The general assumption in Serbian political circles is that Ms Brnabic's appointment is window-dressing. Serbia wants to join the European Union, and the government would quite like to divert the EU's attention from a few little image problems: Its close ties with Russia, its hostility to refugees and rampant corruption.
So what could be better than a woman prime minister who is openly gay and even has foreign antecedents? Why, the Serbs are even more enlightened than the Irish! We should make them full members of the EU as soon as possible!
That may well be the plan -- and if it is, so what? The European Union knows that there was a considerable amount of calculation behind Ms Brnabic's appointment, but it will not condemn Mr Vucic for trying to make Serbia look like a suitable candidate for EU membership.
Lots of ordinary Serbs will be shocked by this assault on "Serbian values", but many will understand that it serves the national interest. And little by little, just because Ms Brnabic is the prime minister, they'll grow less uncomfortable with the notion of gays -- and indeed just women in general -- having a legitimate role in public life.
This is how change really happens: Not sudden enlightenment, but a gradual acceptance of new rules and values. And the most encouraging takeaway from this little story is that even a man like Mr Vucic, once an ally of the murderous demagogue Slobodan Milosevic, understands the new political and social rules of the West.
They are not yet the new rules everywhere. Eastern Europe is way behind Western Europe, North America and Latin America, largely because it spent between 40 and 70 years isolated from the rest of the world under Communist rule. The struggle is still intense in parts of Asia, and it has scarcely begun in most of Africa and the Muslim world.
Gay rights, feminism, human rights in general are not really "Western" values: A hundred years ago the West was just as intolerant of difference as everybody else. The change came to the West earlier mainly because it is richer, but we're all travelling on the same train, and the other end will pull into the station, just a little bit later.
