Nah from posts on these very forums it is very common for people to view toxic antisocial behaviors as normal.
Decisions made with zero concern for others is indeed toxic.
It seems to me WoW just has a lot of people with personality disorders playing thinking their behavior is okay.
You say toxic has lost meaning due to non-toxic things being labeled as toxic.
I say it is the opposite in that people think toxic things are non-toxic.
The community lacks the ability to define toxicity because they are so toxic they read toxic behaviors as normal.
Ima go with “tossity” cause I imagine a lot of the people who abuse “toxicity” are toddlers and “tossity” is how I imagine a toddler pronouncing “Toxicity”
