We need to be clear on what the Bible says on gay relationships. Sexual acts between males are censured, but there's no condemnation about love between two people of the same gender.
No one can know the nature of the relationship. No one else can know the sincerity of their love, or how they express it.
The irony is that, by reaching baseless conclusions about the gay couple and refusing to deal with them, these "Christians" are in violation of the words uttered by Jesus Himself in Matthew 7:1: "Judge not lest ye be judged".
