What other people do in the bedroom is their own business and their own choice. I respect that, and so should she. It doesn't happen to her, she doesn't have to see it, and it doesn't affect her in any way. She isn't an authority on what is right or wrong, no one is. It is'nt her right to make other people feel bad or wrong for private and personal choices they make that do not affect her in any way. No one wakes up very happy to be gay, they are ridiculed at best and at worst they are targeted for hate crimes, they have no rights, they are singled out constantly, they get fired and judged all the time for their sexual preference, it cannot be easy to decide to live such.

Folk like her are narrow to the point of looking stupid and very disrespectful of fellow humans. I wouldn't lower myself to argue with her. Sure she could use some teaching but if she doesn't want to learn you can't make her.
