Homosexuality is not about love, it is about sex. Sexuality is sexual attraction and participation, thats why its called sexuality.
Despite current teachings, we can live a healthy, even happy life without the fulfillment of sexual desires. These are things that can be ignored for the sake of doing right. Many Christians do it. And yes, many of them deal with stress and frustration, but I know someone who is openly gay who very much acts the same way, so dont let someone who supports the lbgt movement deceive you with such an argument : p
We can love our brothers and sisters without engaging in sexual acts with them. Jesus loved us enough to die for us, that included the men who followed Him and listened to Him. I have a male friend, I love him enough that I feel Id sell everything I owned just to help him if I needed to. But I know its wrong to engage in such behavior with him.
Those who do practice this lifestyle are following an urge to do this, of course its entirely possible for someone to form a strong attachment to someone of the same gender like they would with someone of the opposite gender, but that doesnt mean they need to do these things with them. Abstinence is not a horrible, life-destroying thing that we seem to believe it is : p
Dont be fooled by the love argument, we can love each other, but we dont engage in perverse acts with everyone we love. Just look at the people around you, they are either male or female. It doesnt take much to realize the two are made to go together : p Two people of the same gender together produces nothing and serves no purpose other than pleasing one's self. The fact that it "doesnt hurt anyone" doesnt make it the right thing to do. We were made for a purpose, and doing the wrong thing is the wrong thing to do, you are doing wrong by doing the wrong thing.You can ignore it for the sake of your own pleasure, but it can be held against you for doing so.
It is not hateful to stand for self control and abstinence. There are many people, even those who have come to the Lord, who deal with this issue. And yes, of course, its God's will to love them, and to support them if they are trying to do the right thing. But we dont support what we know is wrong. And you should know that if you tell people that doing the very thing they want to do is wrong, theyre not going to like you : p
