If you looked at the adjacent comments you would immediately see a combination of "western christian values," and open pondering that "Epstein is an Israeli asset. Democrats and Republicans have loyalty to Israel." This alone is enough dog whistling for at least my neighborhood's dogs to start acting up.
To put it into terms that may hit closer to home:
Remember Vatican 2? you may have heard about it. pretty big deal, lots of changes in the catholic church, made a whole bunch of news, put the latin mass out to pasture and also pulled back on the doctrine of deicide, ruffled a lot of feathers, etc.
There are some people who yearn for the aesthetics and cultural heritage of the latin mass. They miss the funny words in a language they don't speak, the historical continuity of the latin liturgy, etc. For these types, it's purely innocent aesthetic yearning, mostly harmless.
There are also some people who both miss the latin mass and feel very strongly about the perfidy of the jews being a theologically important teaching. These anti-semitic sedevacantist types share the same information ecology with all of the more harmless latin mass types. Dog whistles are a tool that can be used to disambiguate between the two types of latin-mass-enjoyers.
Fetishizing "western christian values" communicates different things when one of the most prominent far-right groups, the proud boys, makes this a central doctrine. If a latin-mass-enjoyer were to tell me they deeply valued western christian values, before airing their favorite anti-semitic conspiracies, I'm likely to predict they're not into latin mass for purely aesthetic reasons.
