There are so many alternatives that aren’t as hurtful and convey so much more information too. It comes across as a mean dig because someone can even if that isn’t the intention at all. As a knee jerk result, you go to one extreme of panic and needing to please everyone who doesn’t matter in the end or you go the opposite and tune it all out.
Something may not be your style or it is offensive/inappropriate to those attending but there are kinder, gentler ways to get the point across. “I don’t personally like this” or “this would never fly with our families or friends” goes much farther than “oh that’s tacky!” which is tossed around so much that it doesn’t have much meaning beyond hurt.
