I don't doubt some proshippers are groomers. There are a massive amount of proshippers, especially outside the west like in LATAM and Asian fandoms so it happens from time to time and other proshippers call it out.
What is true is that there a massive amount of evidence of vocal antishippers being guilty of sexual harassment and abuse among other things. https://ultimate-shipping-sources.carrd.co/#documentation I think it's a symptom of a patriarchal problem where weird groups are scapegoated to draw attention from normies who actually commit sexual abuse because it's normal in this kind of society.
It should be that insignificant, yeah. But it has gotten people doxxed, sexually harassed, and driven to suicide. Thus this drama warrants concern.
What do you have against the unemployed? I'm disabled. I'm sorry for being unemployed. Maybe if working conditions were much better I could work.
