Groypers are seething because Nick instructed them to. Nick is seething because in true homosexual cult leader fashion he fears anything outside his sphere of control that would bring his cult members legitimacy like a wife and children.

You see, malevolent gays like Nick will actively discourage their cult members from finding happiness or fulfillment outside the cult because such independence undermines their control. A content, self-sufficient individual is less likely to remain dependent on the cult’s structure, ideology, or the leader's authority. By fostering a sense of fear, inadequacy, or unworthiness, evil homosexuals like Nick can manipulate followers into believing that the only path to meaning or happiness is through their prescribed teachings. This dependency ensures loyalty, compliance, and often financial or emotional exploitation, which sustain the cult and its Nick’s power.
