Although I don't agree with the bi-sexual lifestyle, that does not mean that you cannot talk respectfully with a person that is into that. I mean in casual conversation. As far as hanging around with them, I personally woudn't go that far. Not because I am passing judgement on them, but I would have no interest in talking with someone that might focus on that subject matter. Whatever the situation is, everyone must individually live by their own personal principles and convictions. I think too many people today just "whitewash" everything into one ideal that if you don't accept it, that means that you are not "normal" like "everyone" else. I don't want to be like "everyone else. I want to be the person God made me to be. I don't hate black people, (I'm married to one) but I really don't like rap music at all. (nor does she) It's just a personal choice.
For example...I used to work a job where every year I would get invited to their annual Christmas party. Although I worked closely with these people and talked and interacted with them five days a week at work, I chose not to "fellowship" with them at their annual party or outside of work. Not because I disliked them, but because I knew that just about everyone there would be getting stone drunk and I just don't want to be around that type of environment. Like I said, I don't dislike bi-sexuals (as people), I just don't agree with the lifestyle they choose to live. Some people I guess look at this as judging, but I look at it as just simply separating the person from the lifestyle they choose to engage in. There is a difference in that. Whenever I and my wife go out to a restaurant and we are served by a gay waiter, I don't call the manager over and request one that is "strait". But I also don't (choose) to go out and "party" with them later.
In answer to your question (finally huh?) I do think you are a good person. Most people generally are. If you choose to be friends with them, that is your choice so long as you understand that with every choice comes consequences. (both good and bad) I chose to marry someone that is of another color and race. Not everyone accepted my choice but it was "MY CHOICE" and mine alone and I have NEVER felt ashamed, embarrassed or EVER regretted that I made it.
