It's incredibly hurtful to see someone draw such sweeping, negative inferences without specificity.
Whenever the word toxic gets brought up, I brace, because it feels the one making the claim is either projecting, or trying to use insults to incite others (https://en.wikipedia.org/wiki/Projective_identification)
Who is the person being abrasive and creating a negative culture here? It's a serious claim, inducing social pressure on onlookers, if they don't support the vague accusation, they feel a party to it.
That post makes it sound like everyone's character at that company is subpar and being done personal favors because of characteristics of how they look? It's a stereotype I keep hearing - as if there aren't good, fair-minded onlookers absorbing the brunt of that. It hurts.
