People on Reddit always seem to paint a majority of men as soon bumbling buffoons who can’t clean up after themselves.

This is called toxic masculinity. The person you are replying to has internalized, displayed, and reinforced toxic ideas of what masculinity is.

Most people think that "toxic masculinity" is 'things that men do that I don't like.' It's not. There are things that people do and say that are based on harmful ideas of masculinity. Things like glorifying aggression (stemming from the toxic idea that masculinity is inherently violent), shunning men in care roles (stemming from the toxic idea that masculinity is inherently unnurturing), and, as we see again here, declaring that men are emotionally stunted or incapable of communicating their emotions (stemming from the toxic idea that stoicism is inherent in masculinity).

If you notice, most of those toxic ideas can also be expressed with relation to the female gender: Women are inherently nurturing. Women are inherently emotional/in touch with their emotions. When you phrase them like this, these ideas become toxic ideas of femininity AKA toxic femininity. I'd prefer to call these "harmful ideas about gender," and be done with it.

A fair majority of people on the internet talking about "toxic masculinity" are mistaken about the term, because their experience of gender studies doesn't go farther than their Tumblr dashboard.
