The fact that something is common, or even might have positive aspects, doesn't stop it seeming weird.

I'm used to the idea that there might be congregations which are overwhelmingly something or other, because of the locality - Irish or Italian or Spanish or whatever, and that colours the style and the singing, and maybe the language used, but that's not quite the same thing is it?

The Catholic church I go to probably has as many Philipinos and Vietnamese these days as it has Irish and English, and at present there's a Polish priest. I suppose that'd seem weird in some places.
