Do I remain silent if they show some degree of affection (is, hand holding, kiss at the table)? After all kids will be present. What if they begin to discuss their relationship, plans of a gay wedding, etc? If such topics are brought up, someone will have to engage in conversation. Silence could be seen by them as a type of approval for their behavior…I agree that Thanksgiving is not the type of venue to cause a scene, since I know a heated argument could easily ensue. There can be a way to express disapproval on my part without causing a scene. Perhaps I can privately talk with my cousin b4 the gathering.
Perhaps your family is different from mine, but I can’t really imagine a situation in which my husband and I would kiss at a table full of relatives, or hold hands, for that matter. I mean, aren’t they rather busy talking? How big is this gathering, anyway? I mean, if they start discussing wedding plans and whatnot, couldn’t you just as easily be talking to Uncle Harold about his fly fishing?
How close are you to this cousin? Do you regularly talk anyway? If so, you might get together with him, or call him, and if the topic of his relationship comes up, explain–but only in a courteous and gentle manner–your beliefs. Example:
Him: “Fred and I are planning a wedding ceremony next year at the local botanic gardens. We’re thinking May or June.”
You: “Fred seems like a really nice guy; I can see why you’re so fond of him. It’s a bit awkward, though…you see, I’m Catholic, and my church’s teachings on gay marriage are a bit out of the mainstream…(go on to explain what they are, and make sure you understand them well yourself)”
Don’t compromise your beliefs, but don’t be rude in the process. He may still see this as rejection, at least initially, but in retrospect–and
if you treat him and Fred with nothing but kindness and courtesy–he will probably see that even if he doesn’t agree with you, you don’t hate him for this, and that you respect him as a human being with all the innate dignity that espouses.
If you aren’t close with this cousin and therefore don’t have that opportunity, then I would focus on not being a part of such a conversation in the first place, and perhaps explaining at a later date why.
Are the kids at the table yours? If so, depending on their ages and maturity, perhaps discuss the matter beforehand. A three-year-old doesn’t need an explanation. A twelve-year-old should have some idea of Church teaching, but know to be polite and courteous.
