I read what he said. When a Pope says we focus too much on a specific issue, it implies he thinks that issue isn't particularly serious. If abortion = baby killing how can you say it's an issue that we focus on too much? If you think it's a gray area then okay, I see that. So is that how Francis sees it?
You are aware that yesterday, the Vatican directly laicized and excommunicated two “dissident” gay-advocacy priests in various parts of the world, after their bishops had failed to act.
The one I'm familiar with was a priest who wasn't just advocating gay marriage, he desecrated the Eucharist and fed it to animals. Even marxist Father Pflaeger in Chicago won't go that far. And even if Francis is a liberation theologist himself I think he does believe in the holiness of the Eucharist so I don't read any pro or con sentiment about homosexuality in these events.
No, you're inferring it. A more likely interpretation is a that if we're spending, say, 90% of the time talking about three issues! then we're not spending a lot of time on anything else. Not obsessing is not he same as not important.
