Very thought-provoking analysis, Adaeze!
When examining the concept of toxicity, it's really important to consider both ACTION and IMPACT. What impact does one's action have on another person?
By that same token, it's rather disingenuous to automatically write off a negative impact of one's misguided action(s) as being merely "hurt feelings." That's very easy for any of us to dismiss, when it isn't our individual feelings being hurt. Whenever there are hurt feelings, it's usually indicative of some greater problematic trend.
