Gay Families: Right or Wrong?

In society, people everyday argue what the definition of normal family values are. In many opinions it seems to me that what is considered a normal family is a mother, father and child/ren. Not everyone is granted a normal family. There are those who belong to one parent homes, living with grandparents or other relatives, adoptive parents, and even same sex parents. Every time I turn around it seems that people agree that they would fight to keep their free rights. Then why, might I ask, do we turn around and try and destroy what it is that we fight for? By determining that a gay couple should not have a child, we are taking away another's free right. Society views gay couples as living immorally and therefore corrupting any child brought into their home. There is the argument about it being unnatural for a gay couple to have a child. My argument suggests that it is not unnatural for these couples to adopt their child or go through the processes of in vitro fertilization. There are single women and unlucky couples who are unfortunately not able to have a child of their own that must do the same thing. So why is it that we are telling them that it's okay and telling others that it isn't? What right do we have to keep our freedoms when we would so easily take it away?
