Using the bible against people like a weapon isn't loving. It wasn't when people used the bible to keep women silent and it wasn't when people used the bible to defend and promote the evil practice of slavery.
Of course some people will be homophobic (or racist, or xenophobic, or other scared of or afraid of "the other"), and some will even try to convince themselves that their prejudices are God's prejudices. We are free to believe in any deity (or no deity) and to beleive whatever we will about our fellow human beings. But, regardless of our beliefs, all people have a right to live lives of dignity and all people should have equal rights.
Hate who you want to hate and even call it love, but don't keep other citizns marginalized. That's where the problem lies.
LesBiGay people are being told to deny who they are, to be ashamed of their very ontology, and to give up the people they love most in the world. You may not think that matters, but if it were you, regardless of how seriously you take the Golden Rule (which is also in the bible you know), would you want to have church and state (which should be separate) try to keep you and the love of your life apart? Of course not.
I don't care if you hate me; i don't even care if you fool yourself into believing that hating me is loving me, just don't try to keep me from having all the rights, privileges, and protections you take for granted. You don't have to bless my relationship, but neither should you try to keep me from having it and from it enjoying all the protections that yours does.
