You can't defeat a movement unless you know exactly who's leading it.
…Not really. Thing is, leaders come and go, but ideas are forever; aka most followers don’t follow the leader, but the idea the leader represents. Hence why, even with Hitler long dead, most of his Nazi beliefs still remain strong to this day, sadly. Case-in-point, you assholes are a thing.
It’s also why American fascism, white supremacy, and neo-nazism are still going strong even after most of you assholes have denounced Trump as the leader of your movements.
So, yeah.
TL;DR: ideas and movements cannot ever be killed just by removing a few assholes from the equation. You can, however, weaken it by combating it with an opposite idea; but aside from that, no.
