I'm against. Recent surveys shown that for the child to be grown up in a good way both mother love and father love is needed. I agree with that, cause I know some people brought up only by mothers or fathers and they have lots of problems in contact with other people. Child may also have problems in the future, because other children, mostly in primary schools, are very unkind to people who just have no mom or dad, so what would it be if they had 2 mothers or 2 fathers. I had problems with some people when I was at school just because someone got to know my parents are close to divorce, which really hurt me in that time.
I live in a very intolerant country, but I'm tolerant myself. I am not against gay marriages, or maybe gay people living together. I know some gay people and they are very kind and funny. But I'm still against gay adoptions.
