Is homo attraction sin? (Orientation, born this way, etc.) All that is a lie. Homo attraction isn't the same as hetero attraction.
The Bible calls it unnatural. Lust can come from attraction. The attraction to a painting, flower, etc. IS a natural attraction.
One can change their mind on what once attracted them.
Can you change your mind on finding attraction in a flower? But can you change your mind about being attracted or infatuated to people. I believe we can.
To say it can't be done for homosexuals is to believe in the false "born this way'ism" being taught in the culture. Even if an attraction persists, the grace of God will continue conforming a renewing mind to change. There can be no more attraction to money, women, sexual lust, lying, cheating, etc. We wait on Him, until we're healed and/or until He comes!
Are we willing to believe it?
1 Corinthians 6:9-20:
9 Or 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 effeminate, nor homosexuals,10 nor thieves, nor the greedy, nor drunkards, nor revilers, nor swindlers, will inherit the kingdom of God.11 And such were some of you; but you were washed, but you were sanctified, but you were justified in the name of the Lord Jesus Christ and in the Spirit of our God.
