This is what a lot of people unfamiliar with academia except for maybe getting an undergraduate degree should understand, the "intellectuals" rarely use their tools against their own premises. All the leftist/Marxist theories are far more vulnerable to deconstruction than traditional common sense. Derrida was basically the only deconstructionist or whatever you want to call these faggots to be halfway honest, every single other person deconstructs until they get the answer they wanted to find. And it always starts from some weird premise they themselves hold but basically nobody else does. This is how Foucault starts with some shit he made up about mental hospitals from skimming a single book and basically ends with the idea that sex with children shouldn't be stigmatized or else fascism wins.
There are some dedicated post-modernists that actually question ALL big narratives and constructs. They are quite rare.
The issue with deconstruction is that it eventually met the hard concrete wall of feminism, blackness and various other diverse identities, which immediately resisted attempts to deconstruct them and universalize their issues.
Since deconstruction was deemed essentially apolitical (which it kinda is), it started to be cynically misused or sometimes abandoned in favor of open identity politics. This is where the image of ruthless power pursuits regardless of reality or truth comes from.
The reality is that deconstruction is a universal acid, it corrodes everything that attempts to be stable, like an identity or concept. Most people that use it are simply too retarded to apply it to their own preconceptions, core beliefs and identity, and then when you challenge them on those issues they fall apart.
You can see numerous examples in these forums, where people want to deconstruct a specific group's identity, but as soon as you shine the same light upon their own group, it's all over. A funny recent example was a Mormon attacking Islam, and then going full retard "it's just not the same, and I also don't mind hypocrisy and inconsistency lol" when the same lens was upon the behaviors of their own prophet. You can witness mountains of this in the race/gender threads, where deconstruction rules supreme (in its most basic, rudimentary form), masculinity is crushed under the weight of its inconsistencies and historical changes/evolution, but femininity is STRONK and never looked at. Same goes for the opposite, of course.
And you can see it in the war threads, where your country is mostly awesome dindu nuffins, while its enemies are spawns of Satan that have long lists of crimes against humanity and are barely counting as humans.
TL;DR - humans are generally retarded, as expected. They see enemy narrative and go "HAH! I am surely incredibly high IQ and I will smash their obvious half truths to bits! Surely nobody will ever try the same shit with what I like!!!"
