Maybe it was spillovers from "Brexit" arguments where some UK people thought any critique of the EU was in support of Tories? I mean, since when is complaining about the EU controversial otherwise? You can still see some bitterness regarding Brexit where brits are mocked for choosing the wrong path etc.

I distinctly recall that the omertà on this particular issue predates Brexit ... by about 15 years. There was a brief outcry when the EU constitution was ratified before the topic suddenly and mysteriously vanished from public discourse (at least, insofar as such discourse took place on mass media).

Ye ok I was too young at the time to notice. I agree with the phenomena though. Unless you look you don't notice really. It is like if someone presses a switch and the consensus changes for no reason at all.
