I don't necessarily believe so. To the extent there are those born with homosexual affections I believe Christ gave them the same redemption as he did all of us sinners if they just believe in him in their heart and repent. If someone who has been saved still has those inclinations (despite sincere effort to pray them away) yet does not act out on them I think you could call him a celibate homosexual Christian. I know all my sinful lusts didn't suddenly disappear when I got saved but the Lord had the grace to give me the strength not to act out on them. Sanctification proceeds at its own pace for each individual. We are all born sinners, some just have different pet sins from others. I understand your point, that you can't divorce the label from the behavior which defines it but I'm willing to concede that some may be born with that proclivity and that you can separate desire from behavior. For the most part it is just a matter of semantics, I think we are essentially coming from, and come down on, the same position.
So, don't get me wrong - I agree with the jist of the entire article. The scouts have been given over and Christian churches should disaffiliate from them and work to promote other, Christian, scouting groups for kids. A lot of denominations already have something similar for boys, now is the time to put a priority on this.
“To the extent there are those born with homosexual affections”
I don’t believe anyone is born with it. It is learned behaviors.
