Michelle,
	You bring up some really good points to be thinking about.
There were three things that I experienced in this light:

1) Some years back up in Chicago, there was a man that I was assigned to, to learn how to go door to door with the gospel.
He showed me that confrontational evangelism, nor debating, work very well at someone's door.
Then at one door, the person who answered told us that he was gay, and waited to see how we would respond.
The man that I was with wanted to talk to him about a Jesus that loves him.
The person at the door said to the man, that if he would be willing to give him a hug, that he would invite us in to hear about Jesus.
The man immediately hugged him and we were quickly invited in.
The man spent a long time explaining the gospel and the love of God, especially demonstrated by the cross.
The person didn't pray a prayer, or ask Jesus into his heart, but he was greatly moved and affected by the gospel, no doubt good seeds were planted.

2) Also, a number of years back, when I was in San Jose for a Mac Developers Conference, I made some discoveries.
When I gave the gospel to multiple people, simultaneously, who all claimed to be gay, that reaction was negative.
The more people together, the more negative the reaction.
Perhaps they feared what the others would think or say, if they didn't go with the flow, so-to-speak, being confrontational.
So, I attempted to to limit witnessing to only one-on-one, where I quickly discovered the reaction to be much more favorable.
That would involve me being asked questions, and their intently listening to what I was saying.

3) Also, back up in Chicago, I had some friends that I would go out witnessing with, and even street preaching with, at State & Rush, and Division.
One of them was more humble than the others, and I only knew him, and about him, as a Christian.
None of us knew anything about the others, before they were saved, and they about me, also.
One day, our church was having a baptism, with a number of new believers being baptized.
That one friend approached our new pastor, and asked to be baptized, and said that he had not been baptized since he had been saved.
He was the last one to be baptized, and before baptizing him, the pastor asked him to testify that he was saved.
That's when he said to the whole church, that he had been caught-up in the homosexual lifestyle.
Then the gospel came to him, and he realized that it was sin, but that Jesus wanted to forgive that sin.
So he asked Jesus to save him, and then he abandoned that sin and lifestyle, and that he had lived free of all that, all the years that he has been saved.
There was a group gasp and silence, by all the good brethren, and he was afterwards shunned and ignored.
This really broke his heart, and he left, and I never heard from him again.
