This "2,000 years of Church tradition" thing would mean less than nothing, I fear, to one of her obstinacy.
(This is one reason why Catholic Bishops must beheld liable for pastoral malpractice, for allowing the continuing sacrilegious reception of Communion by these people who despise the Lord of Life. It would be pastoral kindness to exclude them formally from the Catholic community, as a difficult but shocking way to make them aware that they are in spiritual peril of the most terrifying kind.)
However, there is a surprising subset of people out there who are convinced that what I'll call "hetero-normed homosexuality" -- in other words, homosexuality lived in accord with some of the values of traditional marriage (with monogamy, fidelity, a life-long bond) ---is a new thing never addressed in Scripture, which, they say, dealt only with rape, prostitution, pederasty and the like. They say no Biblical figure, OT or NT, ever alluded to, or even imagined, let alone condemned, a consensual marriage-like bond between two equal adults pledged to a union of life until death.
Such people need to see that 2,000 years of Christian teaching shows the authentic way in which we are to understand these Scriptures, since Jesus Christ promised that the Holy Spirit would guide the his church.
You may be familiar with Dr. Albert Mohler, a respected Baptist theologian (much respected by me!) who has concluded the same. Faced with this surprisingly large group of exegetes with this revisionist view of what the key words mean in Hebrew and Greek, he argues "Does not God guide the church? And has not the church been absolutely opposed to genital relations between two people of the same sex, from the times of the Apostles until now?
He argues on the basis of "the mind of the church" as the key to correct exegesis. Which, I think, is wisdom on his part.

That they say it and that scripture says otherwise are two different things.
The Laws of Moses CLEARLY condemns same gender sex and so does the Book of Romans written by the apostle Paul.
It isn’t that Scripture is not clear on these things, it is that people will want to rationalize what they believe no matter what.
Similarly, you can appeal to church history or your bishops or priests can say that the Catholic church calls homosexual acts a sin, if a person refuses to accept it, it is to his spiritual condemnation. A Politician like Nancy Pelosi WILL rationalize anything regardless of whether scripture teaches it or LIVING church members teaches it, or even when the Pope clearly teaches it.
As for Albert Mohler, he clearly appeals to scripture in his arguments:
when it comes to sexual behavior, He maintains that the rules are clear and consistent. He writes:
See here:
The Bible’s commands on sexual behavior, on the other hand, are continued in the New Testament. When it comes to homosexuality, the Bible’s teaching is consistent, pervasive, uniform and set within a larger context of law and Gospel.
The Old Testament clearly condemns male homosexuality along with adultery, bestiality, incest and any sex outside the covenant of marriage. The New Testament does not lessen this concern but amplifies it.
The New Testament condemns both male and female homosexual behavior. The Apostle Paul, for example, points specifically to homosexuality as evidence of human sinfulness. His point is not merely that homosexuals are sinners but that all humanity has sinned and fallen short of the glory of God.
