OK, maybe real life examples are in order:
I live in San Francisco, California (think of what this city is known for). I have my opinions about homosexuality. They’re in line with those of the Church. My friends and acquaintances know that I’m Catholic. They’re also neither stupid nor oblivious so they certainly know what the Church thinks of homosexuality. I don’t think I’ve ever once been asked what my opinion about homosexuality is, and so I don’t give it. There are rainbow flags everywhere in this town. I can’t go a single day without seeing two men or two women showing public displays of affection. I don’t go around constantly pointing them out and saying “That’s a sin! Mmmkay!?” If for some reason somebody in my life couldn’t put 2 and 2 together and deduce my opinion about homosexuality, and asked for it I’d share it with them using the gentlest words I could think of. They’re my opinions and you asked!
When it comes to the societal issue of same-sex marriage, I generally support it. During the Prop 8 fiasco here in California 10 years ago I voted “No” (as in I supported keeping the new, judicially imposed status quo of legal, secular marriage benefits being extended to any two individuals irrespective of sex/gender). I wasn’t Catholic then, but I’d probably vote the exact same way today. I know what the hysterical crowd on CAF thinks. I don’t care what they think. I’ve thought long and hard about this, I’ve prayed about this, I’ve spoken to multiple priests and a bishop.
Before 2015 this caused me some grief with my fellow Catholics because the laws were not yet settled in the United States as a whole, instead there were a patchwork of laws across various states, and in some cases the legality of same-sex marriage was oscillating back and forth either due to judicial fiat or voter fickleness. In 2015 the Supreme Court ruled that same-sex marriage bans violated the federal constitution and over night gay marriage was the law of the land in all 50 states and territories of the United States. Barring some huge 180° turn in Supreme Court jurisprudence (which is very unlikely) or an explicit amendment to the federal constitution defining marriage as heterosexual and monogamous (even more unlikely), same-sex marriage isn’t going anywhere. It’s done.
Today, among my Catholic acquaintances, fellow parishioners, etc. I never hear same-sex marriage spoken of. It’s just not even on the radar anymore. It’s like no-fault divorce. We’re still against it in principle. If we’re asked for opinion about it we’ll offer it. We aren’t making a huge stink about it because, really, what’s the point?
