Not Fear, But Love

How would I respond to this? I suppose I would respond with my character more than anything. This passed summer I worked with three females who were all lesbian, and one got married while I was still with them. I never hated, I never treated any of them any different. I actually became good buds with them all, proved myself through hard work (I was a Restoration Laborer) and deep, insightful conversations. If we had ever discussed the topic, I do not think they could accuse me of being that kind of hateful, judging person. If at all possible, I would prove with my character that real Christians know how to say "I love you, I just cant "walk" with you" (walk meaning the walk of lifestyle). I would know, then, how to assert this point. What good does it do for either persons' agenda if I hate? Besides the feelings that would get stirred up, which would lead to no good in and of itself, but logically, what good would come of that? There is plenty of evidence after mentioning this - Biblical, Scientific, and all the crossroads of the two - to support where I stand and how I choose to act about it. How exactly I go about introducing these things and just how successful I am will depend on the temperament of whoever I'm talking to.
