Get ready to have this right wing (some might say fascist) talking point coming out of every GOP mouth until November. 
I think folks too often forget that, domestically, the Cold War was a culture war. We remember McCarthyism as a bad mistake "we" made, but we forget that red baiting often worked. There's a reason conservatives loved calling MLK a "pinko."
It's no coincidence that the official "culture war" was kicked off by the right (or officially named as such) in the early 1990s, right after the actual Cold War against "the totalitarian commie threat" ended. They needed a new existential enemy, & the culture war provided it.
The Cold War culture war was partly about silencing leftists, but mostly it was about preventing moderates from taking progressive ideas seriously. "Hey white kids, don't be concerned about segregation, because those Civil Rights leaders are just commies in disguise."
Likewise, the culture war of the early 90s (as I experienced it as a middle class white youngster) was about trying to encourage non-reactionary straights to see things like the gay rights movement as a sinister "gay agenda" that threatened the sinews of American culture.
Rhetoric like Orban's (that the Trump folks will undoubtedly adopt regardless of who the Dems nominate) is aimed not at his supporters who are not at risk of leaving him, but instead at those squishy folks in the middle, often low-information voters.
One thing worth noting is that the American right, including (and even especially) the "reasonable, responsible" right, has been yammering on about the monolithic and incipiently totalitarian "left" for decades now.
There's a reason why the American right has doubled down on the reductive binaries that drive the culture war. Because they often work well enough to scare a sufficient number of moderates into voting Republican. The "gay agenda" of 1992 is now "the transgender agenda."
Talk of the "pinko Civil rights movement funded by a secret cabal of Marxists" of 1967 is now talk of the "radical, anarchist Black Lives Matter movement funded by George Soros." Reducing progressive movements to terrifying caricatures of themselves is old hat, & it often works.
