Should sexual orientation parents adopt children?

In the article "Gay Adoption Debate and Poll" (http://www.youdebate.com/DEBATES/gay_adoption.HTM), it lists some existing fact and some pros and cons opnions toward homosexual adoption issue. The facts it mentions according the exact number of children adopting by at least one sexual orientation parent (1.4 million) , the vast majority of states in United States no longer deny custody or visitation to a person based on sexual orientation, and only Florida's law bans the homosexual adoption. The article also point out some pros about the issue.
In the pro sides opinions, first, the researchs show and unequivocal fact: homosexual adopted children grow up as successfully as the children of heterosexual parents. Second, there is no evidence show homosexual parents are unfit for parentality. Third, Home environments with lesbian and gay parents are as likely to successfully support a child's development as those with heterosexual parents. In addition, the fourth pro opinion, the children of lesbian and gay parents grow up as happy, healthy and well-adjusted as the children of heterosexual parents.
On the other hand, about the cons. It claims
1. Social science evidence agrees that the best environment for the well-being of children is a household with both a mother and a father.
2. A homosexual environment, on the other hand, can model homosexual behavior to children.
3. London researchers Susan Golombok and Fiona Tasker found that children raised by a homosexual parent were much more likely to experiment with homosexual behavior themselves.
The main courses of the con opinions in this article are surroundding by emotionally and mentally healthy child concepts. In the con ideas of the article, it say, "Stability is the key to raising an emotionally and mentally healthy child; unmarried and homosexual partners simply cannot provide the stability that married heterosexual couples can give." It is the main claims of the con ideas.
In the article, we could see the truth and opinion and declaims from both pros and cons. It help audience to make a clear concepts and the situation of the homosexual adoption issue. It is a issue which have been broadly disscussed in the US as well as other countries. Everyone holds various ideas and opinions from different sphears. In my opinion, under the view of "Everyone was born equal, and the concept of everyone should have his/her rights to pursue happiness, including forming a family.", I believe the homosexual couples can and should not be banned if they want to adopt children.
