Swiss voters look set to back a proposal to open civil marriage and the right to adopt children to same-sex couples on Sunday. Swiss broadcaster SRG projected that 64% of voters had voted in favor of same-sex marriage in a nationwide referendum conducted under Switzerland's system of direct democracy. A final result is expected later in the day.Amnesty International said in a statement that opening civil marriage to same-sex couples was a "milestone for equality."In Carouge, voters were mixed.(UPSOT) This voter says ''what is important for a child is to be loved and respected and I think some children are neither loved nor respected by heterosexual couples, so I don't have any issue or reluctance.""To my knowledge, it is not as easy for straight couples who have difficulties to have children compared to what is planned for non-straight couples. So, this is the main reason and on the other hand, I think children need a dad and a mom."Married lesbian couples would also be allowed to have children through sperm donation, currently legal only for married heterosexual couples.It will also make it easier for the foreign spouse of a Swiss individual to get citizenship.
