The question is whether the same sex ceremony is alleged to be a "sacrament".
Please note there are "high church" Protestants who do that, so it's no inconceivable such a thing is in the works.
Doesn’t matter who does it, it is blaspheming our Lord.
Also does not matter one whit if it is a sacrament or blessing, both are ignoring the sin being brought front and center. Both are encouraging (even if tacitly) the act which is in reality the real focus of these events, all of them have been about celebrating homosexuality.
Sacrament or not, ANY church that encourages or requires clergy to bless fornication and/or homosexual behavior - is a reprobate church! The Lord is calling Francis and all clergy who think like him on this subject - to repent.

Excerpts from above cited Catholic Catechism:
A. Basic Moral Principles
1. All sexual acts, outside of natural marital relations open to life, are intrinsically evil and always objective mortal sins.
2. All unnatural sexual acts are intrinsically evil and always objective mortal sins.
3. All sexual acts between persons of the same gender are intrinsically evil and always objective mortal sins.
4. Sins are acts involving the intellect (knowing) and the will (choosing). An orientation is not, in and of itself, an act or a sin.
5. The homosexual orientation itself is intrinsically evil, but is not itself a sin.
6. Since the homosexual orientation is intrinsically evil, any and all acts, whether sexual or not, by which a human person knowingly chooses to move toward, cooperate with, reinforce, or act upon, a homosexual orientation is itself a sin, either venial or mortal.
7. All human persons are children of God. No human person is intrinsically evil, even if he or she has an intrinsically evil sexual orientation.
8. All human persons inherently deserve just and merciful treatment.
9. The promotion and spread of homosexuality is offensive to God and is gravely harmful to families, the Church, and society in general.
10. Society has the right and the duty to make laws which discourage sinful acts that cause serious harm to society. Please note there are "high church" Protestants who do that, so it's no inconceivable such a thing is in the works.
