The trouble with using the word “gay” is that people mean different things by it. In discussions on this subject among Catholics, people usually make an effort to distinguish between the attraction and the action. This of course is because we recognize that unwanted attraction to the same sex is not a sin in and of itself; rather it sexual actions with someone of the same sex that are disordered and immoral. (I.e., a person has little or no control over who he is attracted to, but he can control his actions.)
Catholics also tend to be aware of the fact that there are many devout Catholics and other Christians who experience same-sex attraction and yet live chastely. However, to most of the rest of the world (including Evangelicals), there is no presumption of chastity with the word “gay.” To most people, if you are “gay,” you either have or are looking for romantic or sexual partners of the same sex.
I am sure that Franklin Graham was referring to people who live a homosexual lifestyle. I very much doubt he was referring to people living chastely. Honestly, I am not sure how many Evangelicals realize that there is such a thing as same-sex-attracted people who choose to live in chastity, although awareness on the subject may be growing.
