I do think there is such a thing as toxicity in social situations. In 2018 I made a big mistake by being around toxic people and my life took a nose dive for around 5-6 months, which im only now starting to crawl out of.
Turns out the people who tend to be toxic are the ones who say toxicity, gaslighting etc don’t exist.
A lot of American life revolves around toxicity: psychiatry, the military, the media, most if not all jobs, our president etc. People who are actively abusive towards others but do it for some (in their mind) noble reason like suppressing social deviance, instilling disciple etc
At the end of the day though I think adults need to learn that their actions have consequences and not everyone lives in a bubble.
