I think there is a dishonest conflation going on here.
Pedophile is literally "you have molested / raped or want to / are trying to molest / rape minor children."
Groomer in this sense is "you are contributing to the social contagion of sexualizing minors, as evidenced by wanting to isolate them from parents to promote homosexual or transsexual identity to minors, especially in a grossly inappropriate setting for ANY OF THIS, such as a goddamn school, and / or you are promoting drag shows for minors / drag queen story hour, etc etc"
The latter isn't even illegal, though it should be, but they're not obviously not 1:1 equivalent.
The mods in this thread have said that calling someone a groomer is accusing them of a crime worse than murder. First of all, no, that's bullshit, murder is worse than pedophilia, murder victims are dead forever and nothing can fix that, and second of all, see above, groomers aren't prosecuted in this country, and it's like pulling teeth to get states to ban "top surgery" on minor girls with punishments for the surgeons doing needless elective non-consensual surgery, let alone mere groomers getting in trouble.
