Homosexuality, if you mean the temptation, is a temptation, not a sin in itself but always a moral danger, due to our fallen nature.
Is it possible for a person who experiences this temptation, to live chastely? Yes, it is. By rejecting the sin in thought, words, and deed; by avoiding the persons, places, and circumstances which conduce to this sin; and by a firm reliance on the grace of God and recourse to the Sacraments.
1 Corinthians 10:13
No temptation has overtaken you except such as is common to man; but God is faithful, who will not allow you to be tempted beyond what you are able, but with the temptation will also make the way of escape, that you may be able to bear it.
This applies to people battling temptations to homosexuality, or alcoholism, or gluttony, or wrath, or avarice, or thievery, or sloth, or marital infidelity, or any other sin.
It is important to make a distinction between the temptation, and the sin.
The Catholic doctrines have never, as you say, "normalized" homosexuality.
There are way too many ignorant, deluded, or proudly dissident Catholics in error about this, but it is their opinion, and not Catholic doctrine, which is erroneous.
Temptation does not define a person. Tempted to steal does not make one a thief. Tempted to kill does not make one a murderer. Tempted to bugger another of the same sex does not make one a homosexual. while temptation is sinful in the eyes of God it is not sinful in the eyes of society. Homosexuality only occurs when it is performed. There is no predisposition to homosexuality that brands one a queer, only the act.
A scout leader who is a professed queer has performed sexual acts on another male. Such persons are not constrained by sexual taboos or moral controls. Unless they turm away from and reject as sinful their sexual immorality they can not be permitted to be in authority over children.
Your attempt to define a person as a chaste homosexual is an aberration and is not consistent with Catholic doctrine.
