Spreading hate is not the loving thing to do.
It's not Christians who hate gays, it's narrow minded ignorant people who are trying to deflect the judgment from themselves, trying to keep the skeletons in their closet hidden. I myself am a straight Christian man and do my best to love as God would want me to. We are not here to judge and condemn, we are here to live our lives as an example of what it means to have God in our hearts and hopefully when all is said and done, make the world a better place.
I know fear keeps people from feeling comfortable and uneasy, but don't let fear become hate, talk to people who are gay and find out why they feel the way they do. How can someone who is not gay themselves, tell you if people are born that way or not, that would be like me trying to tell you how it feels to be a woman, it's just not possible and doesn't make any sense. Don't be ignorant, be educated and make an informed opinion, and if you still don't agree with it that's fine, from that point forward just live and let live. You don't have to agree with it, just don't try to destroy it, because I'm sure there are many things people could find about your life they don't agree with too.
If you ask me, the whole "sanctity of marriage" argument is a bunch of nonsense too. If you haven't realized it yet, straight couples aren't really keeping marriage all that sanctified. We need to focus on ourselves first, work to make us the best we can possibly be, before we go trying to tell others how to live their lives. If you're room is a mess it would be hypocritical to try to tell others to clean up theirs without cleaning up yours first.
As far as Chick-fil-a is concerned, I'm not against Dan Cathy speaking his mind, he's entitled to believe as he feels fit. I just think if he really wanted to preach about family values and love he would have come forward to tell his supporters not to hold a Chick-fil-a appreciation day to further fan the flames of hate? If you're going to speak on love, go all out, if you're only going to do the job halfway, then just keep your mouth closed.
I don't believe God makes mistakes, I believe in the beginning he did want marriage to be one man and one woman to ultimately populate the Earth, but now seeing the end result and how corrupt people have become, he decided to send in the gays. No more unwanted children born into this world and to make things even better, they are willing to take care of the children that are in need of love and companionship from others. Ask a child who is hurting for a hug if he/she cares what sex the people are who give it to them. Teach your kids love and tolerance and hopefully one day in the future, this world would be a better place for all of us.
This message isn't about being pro-gay, that's your business, it's about being anti-hate. It's not what God you follow (or don't), it's not your sexual preference and it's not how you look that makes you evil, it's what's in you heart.
