The term masculinity is supposed to refer to cultural trends within sex that influence behavior, not the actual behavior. Since we live in an incredibly complex and diverse society with many subcultures, trying to define what exactly our society promotes as masculine is ambiguous. What someone would anticipate of my behavior based off of my sex is widely different in various parts of our culture.
This doesn’t even comment on the word toxic. The word toxic should never be used in social sciences. Social sciences should remain descriptive. For example, the Austrian school doesn’t prescribe libertarianism, and it doesn’t say anything is bad or good … it is valueless. Of course, most fans of Austrian economics are libertarians because they like people and they believes libertarianism is good for people based off of their ideas in Austrian economics. However, someone could be a communist tyrant and fully comprehend and believe in Austrian economics … they’d just have to hate people.
The term toxic masculinity is a shit term that is only useable as propaganda. The fact that each word in the term is so rich in content but people don’t tend to define it shows that it is used as propaganda, and the term is being predominantly used by people claiming to be social scientists but are really just propagandists.
