I'm a biromantic asexual, so fairly familiar. I'm in groups with other gay/bi Christians (one of the groups is side B, the other allows it's members to be side B and their official stance is that is a legitimate position to hold), and have been able to gain some insight from there. I've been in LGBT spaces for years as well.
One big thing with side B is that we don't vouch for conversion therapy..
questdriven, you say that homosexual, bisexual is merely a description of one's attractions, but not their actions. Thus one can be rightfully be called a gay Christian, homosexual Christian, bisexual Christian etc., so long as they don't act on their desires.
But is this the way God uses the term and wants the term used?
1 Corinthians 6:9 Do you not know that the unrighteous will not inherit the kingdom of God? Do not be deceived: neither the sexually immoral, nor idolaters, nor adulterers, nor male prostitutes, nor homosexuals. (Mounce)
Is God here (through Paul) saying that anyone who has homosexual attractions will not inherit heaven? I don't think so. I believe there are people who struggle with these attractions, and put them out of their minds and have victory. These, therefore, should rightly be called former homosexuals, in that they've forsaken that lifestyle for the Gospel.
My fear is that you're encouraging people to hold onto the homosexual bisexual label giving it existential power over them. My fear is you're doing this to yourself. I don't think this tactic jives with the Gospel message. You mean well. You believe you're reaching people, but I wondering if your'e merely appeasing them and stopping them from fully renouncing homosexuality.
