No, science is always science. Just because the media portrays certain things as "scientific truth" (or, for that matter, scientifically unsure) doesn't make it so.
Indeed, even if scientists claim something bogus, that doesn't make it science.
So...actually, yeah, it's a lot like the argument that the USSR wasn't real communism, any more than the Democratic People's Republic of Korea is democratic. People claim it to be X, other people take that claim as gospel and use it to paint X as terrible, despite the fact that the people making the claim are full of shit.
The argument that the USSR wasn't really communism isn't a semantic argument of "yeah it was a marxist utopia" but rather one of whether we support governments claiming to be communist. We don't have an example of successful communism, while we do have examples of successful science.
I have literally never seen that argument, and frequently seen the argument that communism (and/or socialism) is Bad, because the USSR was communist, and they were Bad.
Not that I'm saying you haven't encountered the reverse; I'm quite willing to believe that people who run in other circles (or make other claims) encounter different arguments. But yeah, I see the "we shouldn't want communism/socialism, it killed millions of people under Stalin" argument all the damn time.
