This is all so goddamned stupid that it is beneath us all to spend any time at all thinking about it.
Buuuut...
This is how the left has operated for the last 50 years or whatever--the real left, the vanguard. Aside from the fact that it's used to advance their totalitarian politics...it's just idiotic. Even when this method--the method of wacko free-association--is applied to nonpolitical subjects...but of course everything is political, bigot!...it's revoltingly stupid.
OMG...a person in a commercial acknowledged that genes exist!!!
This, in fact, is a major ground for the outrage. As with open borders, the left didn't just wake up one day and say: OK, that's our view, then. They just slowly became more and more permissive about borders, slowly began using arguments that entailed that it was wrong to keep people out, wrong to kick people out...and so on...until finally they held a de facto open borders position. Kinda the same with...gasp!...genes! The left's de facto orthodoxy is blank slatism and "social constructionism." Race has become "race" (in "scare quotes"), it is (of course) "socially constructed" (no scare quotes there, bigot!) and just what that means is...well, far too difficult and theoretical for you to understand...so just take their word for it... Now, infamously, they've begun to try to "deconstruct" the male/female distinction, too. Believing in genetic differences and natural kinds--verboten! If you believe that there are genetic differences among people, you must be a Nazi and think we should be stamping out some of the responsible genes. If you believe there are genetic racial differences, you must believe some races are morally superior and some inferior. Ditto sex.
This ends up, in the gibberish-filled, sophistry-addled screeds of the left, meaning ...Genes...something something something...Hitler!!!
And this, of course, is how our old friend Trofim Lysenko actually started out: denying the reality of genetics.
As Cooke points out, there's also a double-standard here. Those standards are:
[1] You evil Retrogrades are responsible for even completely daft, made-up implications and associations of your utterances that we spin out of our fevered, free-associative, Derridean/Freudian imaginations.
[2] No matter how clearly WE, the anointed, say something like 'we must dismantle whiteness' or 'defund the police,' we must never be held responsible for meaning what we meant.
The Sweeny ad is pretty dopey stuff. The actual text/dialog confuses genes with their expression...OMG!...too bad Madison Avenue didn't hire me to critique their work! But the sophistical attempt to make it all Nazi is typical leftist bullshit.
The left is forced to accept more and more insane views to defend pronouncements of this kind. They've got to deny one of the following in order to defend this latest bullshit:
[a] Genetics is scientific
[b] Genes are responsible for traits like blond hair, blue eyes, and general attractiveness
[c] It's better to be attractive than unattractive
Then, of course, there's the issue of intent. Did American Eagle--and Ms.Sweeny!--intend for this to be a call for eugenics--and Nazi eugenics at that!--? The left has two answers, and they flip-flop back and forth between them, depending on their rhetorical/political needs:
[i] Intent doesn't matter, bigot! We have already proclaimed the Death Of The Author! Interpretation is king! All that matters (waves hands) is interpretation! And we have so interpreted it!
[ii] Of course that's what they meant--what else could it possibly be?
It's the irrationalism at the heart of all this that most repulses me. Its association with totalitarian politics is--almost--just icing on the cake...or whatever the opposite of that is...some bad thing that makes another bad thing worse...YOU KNOW WHAT I MEAN
Of course another, peripheral, danger here is that real racism and something like Nazism is actually starting to make noise on the fringes of the right... That's a real thing--but it's beside the point. People don't want to take on the behemoth of idiocy that is the intellectual left...it's much easier to say "Well, this could help out actual racists/Nazis." Thus tacitly falling into another standard leftist sophistry: the only way the left can be wrong is to inadvertently help out the right.
It's not the only way--not by far--but it is a way.
