More than that, it’s the only political route where Kim will get repeatedly tired of your shit. Anything else, even being a commie, he’ll entertain. He might think you’re weird or embarrassing, but he won’t raise his voice. The fascist route gives you multiple lectures where Kim calls you a racist piece of shit, culminating in a fight where Kim refuses to have anything beyond a professional working relationship with you. To become a fascist in DE involves betraying the one person who believed in you from the start.

Among other things, that's why I'm treating it like the Undertale Genocide route and won't be touching it with a 10 mile stick.
