The coordinator of the DDoS attack (Who I am apparently not allowed to say the name of or my comment will be instantly flagged after posting) is being persecuted for their shady history and actions, which includes being a prostitute and sponsoring the (paralegal?) distribution of transgender hormones to minors.

Both sides employ a public figurehead who abuses their para-social relationship with their supporters to extract donations from them. So in this sense, the "persecution complex" is an artificial mechanism whereby they drum up support.
Who is being persecuted? For which beliefs? And how are they being persecuted?
