You didn’t answer the question I asked. You wrote: “If Trump went away the truly deranged would replace with him a new enemy/hero.”
You were talking about obsession. Obsession means an unhealthy and compulsive preoccupation with something or someone. Clearly, the MAGA community is obsessed with Trump. They go to his rallies, they believe everything he says, they even say he was sent by God. If your understanding of TDS is based on obsession then obviously the MAGA cult is rotten with TDS. If Trump were to disappear everyone else would sigh with relief and maybe spend a minute trying to forget he ever existed.
