The Church's position in general is that everyone is immoral and going to hell without the Church's help. (See original sin, the sacrament of confession, etc)
He isn't saying "gay is now ok." The pope is saying that the sin of homosexuality shouldn't be treated any different than the sin of lying, greed, stealing, envy, cheating, murder, child molestation, etc.
I think the quote from him below expresses his viewpoint with more nuance than I could:
"The door is open to everyone, everyone has their own space in the church. How will each person live it? We help people live so that they can occupy that place with maturity, and this applies to all kinds of people."
"What I don't like at all, in general, is that we look at the so-called 'sin of the flesh' with a magnifying glass. If you exploited workers, if you lied or cheated, it didn't matter, and instead relevant were the sins below the waist."
"We must not be superficial and naive, forcing people into things and behaviors for which they are not yet mature, or are not capable. To accompany people spiritually and pastorally takes a lot of sensitivity and creativity."
"Everyone, everyone, everyone, are called to live in the church. Never forget that."
Yes, modern religion has many rules made by the dicks once they took over. Before the dicks rules were things like don't steal shit, don't fuck your neighbor's wife, don't murder people, don't lie about shit, etc. The dicks were so bad that some other guy had to come along and say "seriously guys, stop being dicks". But the dicks didn't like that so they killed him.
