It hits these freaks exactly where they hurt, which is in their need for validation. They live in a hysterical relationship with "normies" - they simultaneously need to look down at them for being "sheeple", while also getting validation for their beliefs from large numbers of people agreeing with them.
Trump mainstreaming their beliefs while being able to shit on libs fed that fantasy, and then half the country going "no, you're weird" just pulled the rug out from under them, and now they're freaking out. The dream is collapsing and it's hilarious
