What does that mean? It seems like a contradiction in terms. How could you have someone who rejects modernist ideology but promotes a modernist ideology?
It's a common cliché from rightwing circles (initially I think the combination of the two was produced by Jordan Peterson). Not to be too mean, but you'll see a lot of the Ben Shapiro fan crowd snagging on to it because it sounds smart despite being mostly meaningless. It's a placeholder for terms like 'degeneracy' and 'cultural bolshevism' and other such social forces that might undermine the status quo.
It is. The ideology that's referring to which is popular amongst politically active young people is frankly a mess. In particular there's a gaping hole in their post-modernism where they just completely fail to apply any of its tools to their own ideological beliefs or power structures, instead using it to prop up their vaguely Marxist and not so vaguely anti-Western ideology.
Anyone who ever actually read Foucault would instantly realize he wasn't a Marxist because he thought it failed to sufficiently describe why the way we produce truth and knowledge shift historically, which more often than not tends to only be explainable as 'progress' after the fact.
