Conflating your opinion with “the truth” does not actually strengthen your position, you know.
Not to speak for him–but I think he might argue it is not his “opinion” per se but as a teaching on faith and morals of the Catholic Church – it is protected from error by the Holy Spirit–this moves it to the realm of truth. This is something that you, apparently do not hold to be true
Do you think that’s the only way to view same-sex marriage? It’s not, even if you accept the idea that homosexuality is somehow disordered (which is a big “if” itself):
- personal freedom: my right to live as I please despite what others may think implies a moral duty on me to allow others to live as they please despite what I may think.
Your personal freedom – your right to live as you please despite what others may think–is limited by many laws. You cant be married to more than one person, you cant be married to an animal, you can’t run around killing people you don’t like, you cant steal, you cant take illegal drugs --your right to live as you might please is subject to a whole lot of rules imposed on you by society. So as a member of society–there are lots of people you are not letting live as they might wish. Anything else is called chaos.
- harm reduction: *these people will be homosexual no matter how the law treats them, so they may as well have somewhat less misery inflicted on them here on Earth before they spend their eternity in Hell. *
- protection of innocent parties: I disagree with how this couple conducts their life, but I won’t punish them in a way that also hurts their children, who I have no issue with at all.
And that’s just off the top of my head.
Even if you accept the (IMO unfounded) idea that homosexuality is a sin, there are still plenty of reasons founded in
actual love, charity and justice to support same-sex marriage.
