Does anyone else feel like calling out bad behaviour is more punished than the actual bad behaviour?

I was recently accosted by someone for bringing up an incident that involved harassment and bullying from some people in a mutual group of friends… well former friends… and the person told me to stop being “CHILDISH.” They even threatened to kick me out of the Meetup group we’re in… which at this point doesn’t bother me. But nothing to the actual perpetrators. Why does it feel like this is more common than I’d like it to be: someone does something wrong and it’s crickets. You bring up the wrongdoing, and YOU’RE the problem?
