I'd never argue that the left hasn't been winning many fights in the culture front in the past 60 years, to say that therefore there isn't a "war" is ludicrous, ridiculous. Of course there's a war, and it's being won by the left. However, this idea that the right hasn't been winning anything whatsoever in cultural terms is... just wrong. Bringing Cthulhu to the analysis as if the shift has been overwhelming is just cherry on cake (albeit a tasteful one).
Only by positing some sort of tautological idea wherein all the modifications = leftism and all that is no more = rightism can one arrive at such patently absurd conclusions, but so is the illusion of the sort of mentality that has been bred in many places: "The only way is forward, the only positive movement is progressivism, the word advanced is just a qualititative analysis on how much to the left a certain society is". It's tautology of the highest degree. All these are truths, anyone who disagrees is a bigot and should be dismissed (how easy it is to fight like this, by declaring victory by fiat).
I could give you plenty of examples, wherein leftism has been defeated, namely the rise of individualism, the rise of "self-made-men" mentality, the "greed is good" culture that is bred in many work places, the complete dismantlement of the unions, the defeat of socialism against privatization and commoditization of every aspect of our lives - and don't even think of bringing the complaint that these are just "economic" issues, for they are first and foremost cultural ones - but I could also bring about the huge defeat of the sexual liberation movement, wherein in every aspect of modern culture, sex is still regarded as forbidden and taboo, while violence, war and murder are regarded as cool and exciting (movies, games, books, whatever). The defeat of leftist ideals both in the middle east and the feedback this has on America itself (the skyrocketing rise of the military complex, the privatization of armies, etc., etc.)...
I can go on like this forever, but I think you get the point: All of these issues are always being changed, are always part of the political and cultural struggles we face in the present and that will define the future. In light of all that is historic, to present the case that the Left is some kind of invincible Cthuluh still blows my mind. Yes, if you look at the really focal issue of gay liberation, yes, it was a complete leftist victory (one that I applaud), but that's just a very small sample of reality.
