Even when they "mean well", they teach you to accept abuse and settle for less
Some days ago I responded to a comment that therapists are not incentivized to disagree with the system, so they won't teach their clients to stand up for themselves or see the world for how it truly is. It's not their job to acknowledge how fucked up the world is and how your abusers did you wrong. Their job is to make you more comfortable with a messed up world and to teach you to accept your place, whether your place is that of a victim or even of an abuser as long as it truly fits with where you are/can be in the hierarchy and how you continue to serve the status quo.
Therapists also don't benefit from no abusers. If a couples therapist tells an abuse victim to leave every single time they see it happening, then they won't have a job. If therapists "specializing" in trauma therapy actually truly helped you, then you would heal too fast and stop paying up. If a therapist is met with an abuser then there's no point in trying to teach them to stop abusing because how else will they have clients, victims of such abusers to handle and treat? They are taught to view our mental illnesses - our reactions to repeatedly having to deal with fucked up actions - as pathologies instead of what would happen to any mammal in constant distress.
I recall my last therapist telling me that she had corporal punishment in school too and that the brain can differentiate being hit by a teacher or being hit by a parent as discipline vs being hit by a figure of authority for no apparent reason other than abuse, the latter being a traumatic memory for the brain. I thought to myself "huh, she really thinks she's helping me with this advice?? This is supposed to soothe my mind? How about we teach people to not hit kids at all????".
Funny thing is I'm less traumatized by the beatings themselves and more upset at the world. Nobody that actually can do something stops evil people because our world is designed to be fueled by evil. THAT upsets me WAY MORE than actual memories of being beaten up. The fact that the therapist simply tried to justify it thinking it'd help me move on instead of acknowledging that our world is messed up was just insane to me. I could tell she really thought she was helping and that makes it even worse.
