People need to stop beating around the bush. Why would anyone think that gays should not be alllowed to adopt? Most of the people who think that gays shouldnot be able to adopt are most likeley homophobic but not all. People think its unfair on the child. Why should a child have to have a gay couple as thier parents/gaurdians? Well why is that a problem if being gay is normal? It shouldn't be a problem! But it is a problem because of the way society thinks. And the reality is what society thinks will always prevail wether something is good/bad.
E.g. once society said women shouldnot have equal rights to men and blacks shouldnot have equal rights to whites. But it wasn't right.
The problem i can see with gays beign able to adopt are quite basic ones. It will ( and i hope i do not offend anyone) create a minority group, of children who have a gay couple as thier parents/gaurdians. It is likeley to cause alot of social pressures and anxiety. It could lead to all sorts. Thats the natural response form all miniorities, wether it be ethnic ect. Its quite sad, but its the likely outcome because of the way the world works.
