I believe that it is okay to be in a relationship with the same gender as you. If you love them and you want to be with them, then that it is okay. I understand if it is against some peoples religion, but I do not believe that people should be discriminated against if they are homosexual. it is okay to be unique!
Upon reading my description, you may notice I am catholic, yes I am. However I completely agree with your argument, except that I don't. Being gay is fine, it is not a choice, you are simply born that way, it is completely okay and it does not make you any less of a person, you have the freedom to be who you want to be, and be with who you want to be with. Marriage is a sacrament of the Abrahamic religions, it is purely a part of religion, until the government got involved and made it more than it was intended to be. I believe if we simply change the government's definition of marriage to something like civil union, so that everyone not affiliated with the church (gay or strait) would be in a civil union with their partner not a marriage. That way marriage can go back to being purely religious. Then if non religious people want to cement their commitment to each other then they can, through civil union, or whatever they choose to call it.
