Same for toxicity, where I actually do not even agree to your definition: toxicity refers to something toxic, you are the one adding the “codependency” aspect but it works well without it. There’s no such thing as “real toxicity” btw. Or should a biologist forbid you to use the term because it originally refers to poisonous creatures and not relationships?
Anyway, would you please consider not trying to gate-keep the use of words?
