I will address these individually.
1) I believe that everyone has the power to choose their actions. Nobody is "born" gay and I feel like that is an excuse. Its simply another temtatin.like drugs or alcogol, and it might be harder for somepeople than others to abstain from it.
=How could you, as a straight individual, even begin to understand, or have the believe that you know what goes on in some ones head? It isn't a choice. You may believe it is, but as you could believe the sky is yellow and you would still be wrong.
2) Gay marriage does not promote family settings. Children should be reared by a loving mother and father, and procreation is cannot happen without a man and a woman.
=Should we start taking children out of single parent homes because they do not have a mother and a father?
3) I have researched this subject thoroughly, and don't consider myself misinformed. I truly believe that people may be born with higher chances of favoringbthe opposite sex, but I don't believe that people are born gay.
=You need to research it more. The brain structure of gay men and women is different than that of straight men and women. You cannot choose that.
4) It's morally wrong. Yes, God lovea everyone, even gays. He also loves murderers and child molesters, but that does not mean that he approves of their sinful actions, so I.don't consider this a legitimate excuse.
=We live in a secular country. That means we are not governed by the bible or biblical laws. Divorce is not allowed in the bible, and we allow it. Remarrying is not allowed in the bible, and we allow that. Women speaking in church is not allowed in the bible, but we allow that. Wearing two different materials is not allowed in the bible, but we allow that. Premarital sex is not allowed in the bible, but we allow that. Women are not permitted to speak out against her husband in the bible, but we allow that. Children are stoned to death for disobedience in the bible, but we don't do that. Worshiping Gods other than the biblical God is not permitted in the bible, but we allow that.
I do not find you hateful in the slightest. But you are very misinformed, even if you don't see it. Misinformed people never see it really.. If they did, they would no longer be misinformed. None of your reasons are legitimate.
If you are in the USA, then think of this. By law, all people are guaranteed equal rights. Marriage in this country is a Civil Right. It is a contract. Something that is Secular, and made religious only if you choose it to be. Holy Matrimony is a religious institution. In this country, Marriage is a secular one.
Here I will quote part of the 14th Amendment.
"All persons born or naturalized in the United States, and subject to the jurisdiction thereof, are citizens of the United States and of the State wherein they reside. No State shall make or enforce any law which shall abridge the privileges or immunities of citizens of the United States; nor shall any State deprive any person of life, liberty, or property, without due process of law; nor deny to any person within its jurisdiction the equal protection of the laws."
And now I will quote part of the Declaration of Independence.
"We hold these truths to be self-evident, that all men are created equal, that they are endowed by their Creator with certain unalienable Rights, that among these are Life, Liberty and the pursuit of Happiness."
