For some years back in the ballpark 70s / 80s, the Guinness brewery company ran a series of ads for their eponymous stout themed:
Guinness: I’ve never tried it and I don’t like it!
They were trying to break into the US market in a big way and make Guinness a mainstream product. At a time when Budweiser, Schlitz, and Pabst were most Americans’ idea of “beer” whereas Guinness was a rare specialty product found only at hard-core genuine English/Irish expat hangouts.
In each episode, the character would loudly protest how they didn’t like Guinness, despite admittedly never having tried it. Their friend would inveigle them to have a sip which they’d take tentatively & dubiously. The ecstatic epiphany would immediately follow. “I’ve tried Guiness and I love it!”
The campaign worked and in the US Guinness Stout became pretty much a mainstream product found in grocery stores and every ersatz “pub” in the land.
Bottom line: I call what @BigT’s talking about the “Guinness effect”, but I don’t think anyone but me uses that phrase.
Yeah, there used to be a sort of meme (before anything was called a meme) about British people distrusting or expressing distaste for ‘foreign muck’ (which might be any kind of foreign food or drink) as ‘only fit for [insert racist term here]’
It’s hard to tell whether this was just blanket xenophobia, or whether that blanket was a closely stitched patchwork of many different pieces of specific racism.
Or devolves, in the hypothetical Princhester creates - it’s not so long ago that “The Anglo-Saxon Race” and “the Gaelic Race” would have been current terms. And racism would be perfectly apropos .
