Where I live, there is no real “marriage” but a kind of contract that has similar results. A same sex couple has the analogous privileges regarding heritage and pension for the survivor as have heterosexual couples, if one of the partners passes away.
There is now a discussion about the possibility of adoption. I do not know the current status. The attitude of the society has changed towards homosexuality, it has become more tolerant and accepting. Young teenagers who discover their sexual orientation are less ashamed and dare to speak up openly.
I think that those obsessed by the fear of homosexuality have some issues about their own sexual identity.
