In this context, toxicity is about whether the other person sees the people around them and behaves like someone who does.

It’s no more about the content of their opinion and how that falls relative to our own tjan it is about their hair color.

It’s about not letting people who treat others this way set rules to the game that disadvantage anyone who is human.
