Cuck (2019)

Alone and afraid, one man decides to take his fantastical fears to the internet. Becoming a popular blogger with the alt-right crowd, he suddenly realizes that he may have amassed more power than he ever dreamed possible. And although there's always been a distinct line between his fantasies and the reality of a situation, that line is becoming increasingly blurry. With each passing day, his worries are starting to spiral into uncontrollable rage based in hysteria, and now they're inspiring others.
