I think you have to understand him in context. He comes from a continent that is not as prosperous as the US, where there is much poverty, people living in favelas, and in his own country in fairly recent memory, persecution, kidnapping and murdering of political opponents (which it appears he played a large role in smuggling people out of Argentina to safety); there were also brutal dictatorships in other neighbouring countries, namely Chile (Pinochet) and Paraguay (Stroessner) . In many places in South America, for many people the most important priority is simply getting enough to eat on a daily basis.
In Western Europe, and in Canada, the abortion fight has largely been lost, alas, and there appears to be little stomach to re-open any discussion of the issue at the political level. The US is thus a bit unique in that regard, in that the debate still shapes your political landscape. In Canada our Conservative government before being elected promised to raise the issue but once in power, realized it was a hot-potato and didn’t want to tackle it for fear of alienating voters. If the Tories won’t take it on, the parties to the left surely won’t, so basically the fight is dead. I think the same in Western Europe, where most countries are governed by coalition governments.
So I don’t think he’s stomping on the pro-life workers as much as raising the flag and saying that there are other pressing social concerns that need to be addressed.
