A good observation, I am indeed asking the detail of the instances where OP noticed toxicity, because a an example would give us a common understanding, so know we are talking about the same thing when we say ‘toxic’ in this context.
I still disagree with you and insist that words (like ‘toxic’) can have different nuanced meanings.
For example you call me toxic for disagreeing with you, while I think it is toxic behaviour to call someone who disagreed with you toxic. Disagreements happen often when people communicate, but most mature people can accept such disagreements without resorting to name calling.
As I do not wish to make assumptions about what the OP is talking about I wish to hear them describe what happened that they thought was toxic, and not to hear the subjective definition of what Stefnia thinks toxic means.
