I am someone who has truly horrible people as parents; they abused me physically and mentally/emotionally, neglected my needs, broke me down, told me they hated me and wished I was never born, and told me I ruined their life for existing. Nothing I ever did or said was "right," I was always criticized. There was also severe mental illness, domestic violence, criminal activity, and substance abuse going on my entire childhood. It's not hyperbole to describe my childhood as 18 years of torture. I've been diagnosed with PTSD due to my childhood experiences.
I talk about it openly online with stranges, I talk about it with my various mental health providers over the years. However, most of my friends don't really know the full extent of the terror I experienced and I'll never talk about it with stranges or just acquaintances.
It doesn't really come up in conversation very often and it's kinda hard to talk about in person. It's hard enough telling my therapists about it. It's also just really embarrassing and I have to REALLY trust you before talking about it IRL.
We have an extremely pronatalist society and nobody really casually wants to hear about the victims that produces. It's not socially acceptable outside an extremely close relationship.
I don't feel the same typing about it semi-anonymously online. I also REALLY feel that I need to correct the cultural idea that "all parents are inherently good."
