The crusades against Harry Potter and Pokemon were near the very end of the Religious Right's era, where they were fading from power and were widely detested but hadn't fully died out and so were still sorta relevant in certain areas so the GOP was still pandering to them
The Harry Potter and Pokemon moral panics were a sign that they were getting desperate and were losing power. This was around the same time that Jerry Falwell accused Tinky Winky and Spongebob of being gay.
The really hardcore shit was in the 80's and early 90's, but it was more along the lines of using the courts and the misinformed police departments to fight back. You didn't have the rioting like you do now, but you did have a pre-internet version of cancel culture, complete with forced confessions and media hysteria.
Even the liberal media got in on it, even if it was just for the extra ratings (see Geraldo Rivera and Phil Donahue's coverage of the Satanic Panic) and major companies bent the knee to asinine demands (most infamously Procter & Gamble)
The West Memphis Three trial was considered the peak insanity of the Christian Right and the Satanic Panic and in hindsight, it was the beginning of the end for them and was the moment where the general public began to turn against the Religious Right.
