Are Christians unloving if they refuse to accept homosexuality?

Mark Sandlin wrote an article entitled, “Clobbering “Biblical” Gay Bashing” http://www.patheos.com/blogs/thegodarticle/2011/10/clobbering-biblical-gay-bashing/
One of the first points Mark makes in the article is basically that Christians are not “loving” if they refuse to accept homosexuality. Is he wrong with that assessment?
– One of the things often cited by those who agree with Mark is that, “Jesus never said a word about homosexuality. In all of his teachings about multiple things, he never said that gay people should be condemned.” Did Jesus not say anything about homosexuality, or did he?
